Heavier batteries to give a higher watt-hours

July 15 [Mon], 2013, 11:54
An important factor to consider is how much laptop battery you need on your laptop. No matter how much battery you have, with the integrated DVD drive and a lot with a 17.3 inch screen, it will be faster. Battery technology, like any technology improves all the time.
Yesterday’s laptops featured Ni-Cad (Nickel Cadmium) batteries, which poisons the environment if disposed of improperly offered, notcheap Inspiron 1750 much up-time (comparatively), and had the annoying habit of remembering how long have you had used them and refuse not work more the next time. Then there was NiMH (nickel-metal hydride) batteries, offered them a longer life, better efficiency, and no memory problems.

The current generation of laptops still use lithium-ion batteries. These batteries offer a gain in efficiency compared to NiMH batteries, with an extremely low flow rate (long shelf life, when loaded) and efficiency for lithium-ion batteries, is moving to new battery technology is slowing down, however. Even if improvements are made, we are to the point where packing as much energy into a tiny space is always a bit dangerous always. If you ever had actual pictures of a laptop computer explosion’ve seen, this is what could happen if the battery goes haywire. Do not be too worried, though, as this is an extremely rare event. A single fire typically causes thousands of batteries to be recalled, though, because there is little room for error, where a burning laptop is affected.
Some laptops claim up to 5 hours worth of up-time on a number of these battery-take with a grain of salt. That’s probably how long would the battery when you put on the blank screen screensaver and did not stir it for 5 hours. Expect more in the range of two to three hours under continuous use battery per share. If you are on flights, trains, buses, or for 10 hours at a time plan to buy a few extra batteries, make sure you have a plug handy, or make sure that you have a model that is a nice add-on function, the battery may have to keep a lot of juice.

Some designs offer a battery plate that fits on the underside of the laptop, by size and a few pounds, but offers many more hours of battery life. If that’s what you need to check for interesting battery setups. Several manufacturers also offer laptops with expansion slots, a variety of peripherals, including a second battery, second battery that can accept double the battery life. If your laptop does not offer you that you may have to buy another of the same battery and want to ensure you receive a charger to go with him, so that both batteries are charged simultaneously (one in the laptop into the charger) . Obviously this is not ideal. If you need it, just for a model that provides the battery capacity you go. Also keep in mind that additional batteries can cost up to and over U.S. $ 200 per piece.

When selecting a battery, the manufacturers often list an amount of “cells”, each cell has a certain capacity, a 9-cell has 50% more capacity than a similar model, 6-cell battery. This is useful to compare directly, but the story is more complex if you wanted to compare different batteries for different laptop. such as Dell and HP laptop battery laptop battery, it is difficult to say which is good. Batteries have a nominal voltage (V) and milli-amp hours (mAh), which when multiplied together give you milliwatts hours. For example, a 14.8 V battery with 4460 mAH to 66 000 milliwatts hours (66 watt hours). You can compare batteries in this way, but keep in mind that different laptops very different performance requirements, which manages the components and how well the operating system can vary the power consumption. Typically, larger, heavier batteries to give a higher watt-hours. A 6-cell battery can be the same form factor as a 9-cell, but the 6-cell will weigh less because there is less chemical that keep it in on that charge.

If you want to have a mobile warrior, you will cheap W953G find that most of the cells and / or most watt-hours, you can get in your model, so you can go 5 or 6 hours without recharging. It is so painful to run our power before you’re ready.

So here are some recommendations on the laptop battery:
Get a lithium-ion battery consisting of cells in the model you are looking for, including a reserve add-on battery that replaces the DVD drive, or otherwise add to the battery which is included as standard. NiMH or, even worse, Ni-Cad are old technologies that are best forgotten when it comes to power laptops, although they still used to power your power tools.

You can get the system with silver styling instead

July 15 [Mon], 2013, 11:10
Upon first seeing the new Sony VAIO Y Series laptop (model VPCYB15KX), your first thought will likely be, “That is a very pink laptop.” Virtually everyone in the PCWorld offices who saw our test unit felt the need to expresscheap KY265 just that thought. Of course, that’s just this particular test system. If you’re neither a 13-year-old girl, nor especially into promoting breast cancer awareness, you can get the system with silver styling instead.

The Y Series is Sony’s first foray into using AMD’s new Fusion CPUs. It utilizes the fastest of the lot, the E-350: a dual-core CPU that runs at 1.6GHz and integrates a Radeon HD 6310 graphics unit. Sony equips the system with a nice 4GB of RAM and a 320GB hard drive, though the drive only spins at 5400 rpm, which makes launching apps and loading large amounts of data a little on the slow side. (You can scroll down to see the PCWorld Lab results.)

On the performance of this processor, I’ll just echo what I have said before: it’s an absolute killer to Intel’s Atom processors, both on core CPU performance and on graphics performance. Compared against more substantial ultra-low-voltage processors often found in more expensive ultraportable systems, it simply can’t keep up. If one calls this a “netbook,” its performance is fantastic. If one deems this an “ultraportable” (as Sony does) and charges more money for it (as Sony also does), it’s a letdown.

And price is really the issue here. At $600, the Y Series makes a relatively inexpensive 11.6-inch ultraportable laptop, but it’s way too expensive to be competitive with most netbooks. Even if I were willing to pay more for the great relative performance of the AMD E-series processor, I can’t see spending more than $450 to $500 on a system like this. It would be easier to splurge if the solid-feeling construction was married to a similar attention to detail throughout the design, but quite a few of this laptop’s key attributes are disappointing.

The Webcam supports up to 640-by-480-resolution video capture in a world where our cell phones are shooting hi-def video. The keyboard’s overall size is good, but individual keys are smallish and spaced far apart; I often slipped off keys or struck two at once. The touchpad has a nice gliding feel to it, but it’s absolutely tiny. The screen’s 1366 by 768 resolution is appropriate for its size, but colors are a little washed out, and viewing angles are poor. I never expect such small laptops to deliver really high-quality audio, but the sound that pumps from the VAIO Y Series’s speakers is especially thin and tinny.

Sony builds in 802.11n wireless, gigabit ethernet, Bluetooth, and three USB 2.0 ports, in addition to front-mounted card readers. That’s good, but par for the course these days. On a system this small, it’s no surprise to find no optical drive at all. Battery life is on a par with other small Fusion-equipped laptops atcheap Vostro 1320 about 5.5 hours. Sony tends to install a lot of value-added software on its VAIO computers, including a drop-down toolbar with access to VAIO programs like Media Gallery, Picture Motion Browser, and VAIO Care, along with third-party applications like Norton Antivirus (30-day trial), Evernote, and ArcSoft Webcam Companion 4. Whether you find these useful or not is a matter of personal taste, but they’re easily removed if unwanted.

If it were just more useable, I’d have an easier time recommending the Y Series laptop, even at the somewhat steep price of $600. But it’s a big stretch to ask that much for a laptop with a keyboard that makes typing difficult, a really small touchpad, and a standard-definition Webcam.

This announcement came as a bit of a shock

May 28 [Tue], 2013, 11:48
The issue of limited range has been an impediment to EV sales since before such vehicles even went on sale. But as The Truth About Cars now reports, Toyota just might have the answer to this problem. The first steps have been taken toward making a battery which uses sodium-ion compound as the positive electrode. This produces 30 percent more voltage than a lithium-ion battery, and it’s estimated T410s Originalthat it could at least double the range of electric cars. It is even estimated that range to extend to 1,000 km (620 miles) with sodium batteries.

Toyota hasn’t said what we can expect for recharge times on these batteries, and a 600-mile range would be something of a mixed blessing if it also needed two days to recharge. But improvements are being made in the area of recharging as well, and sine Toyota has s
aid that they don’t expect the sodium batteries to be ready until 2020, it’s still a bit early to say what conditions will be like when it comes time to actually charge the batteries. One thing we do know will get better along with range is price. Sodium is one of the most abundant elements on earth, and Toyota says the new T420 Original would almost surely be cheaper than the lithium-ion batteries we currently use.

This announcement came as a bit of a shock, as it was just a couple of months ago that Toyota announced they would be scaling back on EV building and that the technology just wasn’t ready for full-scale implementation. We can only assume that this research is being conducted as part of Toyota’s desire to remain the world leader in hybrids. Whatever their motivation, we’re marking off 2020 on our calendars. It should be fascinating to see how this impacts the market and even whether the technology will spread to other devices which use batteries as well.

It is also developing zinc-air batteries

May 28 [Tue], 2013, 11:47
The highlight of the video is a technician filling the test car with distilled water, while the projected range is shown rising on a display on the CEO's mobile phone. The water serves as a base for the electrolyte through which ions pass to give off the energy that powers the test vehicle's electric motor. In the test car, the T400s Originalwater must be refilled "every few hundred kilometers"--perhaps every 200 miles.

Very simply, an aluminum-air battery uses an aluminum plate as the anode, and ambient air as the cathode, with the aluminum slowly being sacrificed as its molecules combine with oxygen to give off energy. The basic chemical equation is four aluminum atoms, three oxygen molecules, and six water molecules combining to produce four molecules of hydrated aluminum oxide plus energy.

Historically, aluminum-air batteries have been confined to military applications because of the need to remove the aluminum oxide and replace the aluminum anode plates. Phinergy says its patented cathode material allows oxygen from ambient air to enter the cell freely, while blocking contamination from carbon dioxide in the air--historically a cause of failure in aluminum-air cells.

It is also developing zinc-air batteries, which can be recharged electrically and do not sacrifice their metal electrode as the aluminum-air cells do.

In a 2002 study, researchers from the University of Rhode Island concluded that aluminum-air batteries were the only electric-car technology "projected to have a travel range comparable" to conventional cars. The study said such T410 Originalare the "most promising candidates...in terms of travel range, purchase price, fuel cost, and life-cycle cost" when compared to cars powered by internal-combustion engines.

Each aluminum plate, says Tzidon, has enough energy capacity to power the car for roughly 20 miles (we'd guesstimate it at perhaps 7 kWh), and the test car has 50 of those plates. The entire battery, he says, weighs just 55 pounds (25 kilograms)--apparently giving it an energy density more than 100 times that of today's conventional lithium-ion pack.

Huawei red crown on the road twists and turns: five-year profit drop

April 25 [Wed], 2012, 12:01
In the "take a second look" on the road, Huawei Technologies Co., Ltd. ("Huawei") and the distance of the leader, Ericsson is getting smaller and smaller, but due to the slowdown of the development of the industry a number of factors, Huawei's net The profit for the first time in five years crash.

Yesterday, Huawei released the 2011 annual report shows that last year revenue of 203.929 billion yuan, an increase of 11.7 percent in dollar terms, Huawei's 2011 revenue of approximately $ 32.4 billion, Ericsson 2011 sales revenue of SEK 226.9 billion, about Hop $ 33.22 billion, less than $ 1 billion gap between Huawei and Ericsson.

However, Huawei last year's profit situation is not optimistic: its operating profit was 18.582 billion yuan, down 39.4 percent; net profit of 11.647 billion yuan, down 52.9 percent.

2011 net profit over the past five years the first crash, at the same time, Huawei's 2011 operating cash flow after the substantial growth in 2009 and 2010, 2011 was 17.826 billion yuan, the decline reached 43.5%.

2011 global economic downturn in some areas councils turmoil, exchange rate fluctuations and other factors on the company's operations caused by a certain influence, The good news is, the world's Huawei employees through continuous hard work, the basic realization of the expected performance. "Huawei rotating CEO Hu thick Queensland in fiscal said in the report.

In 2011, Huawei set up three major business group (BG, Business Group), carrier networks, enterprise business and consumer business, Huawei Annual Report, these three operations last year, respectively, to achieve revenue of 150.145 billion yuan, 9.164 billion yuan and 44.62 billion yuan, an increase of 3.0%, 57.1% and 44.3%. The ceiling of the business operators and the slowdown in the growth trend is very obvious, and the newly established corporate business and consumer business has become an important engine of Huawei's revenues continued to grow.

For the company's net profits have fallen sharply, Huawei explained that to a large extent by the impact of foreign exchange losses, excluding the impact of foreign exchange losses, Huawei says 2011 net profit fell 36.6 percent, and profit performance in line with expectations.

In addition, because 2011 is the year of the layout of Huawei's new business, Huawei in their business, consumer and business new business areas to strengthen investment in the field of carrier networks, in a volatile macroeconomic situation, the operator control of the CAPEX spending. formed a greater price competition, resulting in the current level of profitability decline.

2011, Huawei in the management structure, try rotating CEO "system, Huawei's 2011 annual report, further explanation and description of this system, Ren capacity as the chief executive officer (CEO) in its annual report beginning with the CEO of speech "part" under the leadership of the board of directors, the CEO of the rotating system identified a statement, Mr Hu, the rotating CEO and chairman of Sun Yafang a statement on the performance of the company.

According to the publication of the Annual Report of Huawei Huawei Investment Holdings Limited 100% employee-owned, December 31, 2011, employee stock ownership plan to participate in the number of 6.5596 million, of all employees elected representatives of the shareholding employees, and by holding shares staff representatives to exercise the rights.

Huawei's annual report for the first time announced in detail the organizational structure of Huawei, the establishment of the Board and the Supervisory Board under the company's shareholders' meeting, 13 members of the Board, elected by the plenary shareholding employees, under the Human Resources Committee, Finance Committee and the Strategy and Development Committee and the Audit Committee, the composition of each Committee also announced in detail.

Huawei, BG is the company's main combat forces, responsibility for the company's growth and improvement in efficiency. The Huawei was first announced by the BG 's CEO: the CEO of the carriers' networks BG Ding Yun, the CEO of the enterprise business BG William Xu, the CEO of the consumer business, BG Yu Chengdong.

Huawei's current organizational structure, especially the system of rotating CEO, Ren said, the traditions of the past is to empower a person, the company's fate tied to the personal body, rotating CEO of Huawei by a small team, because different businesses continue to adapt quickly to changes in the environment can manipulate their decisions collectively, to avoid the rigid personal overly paranoid company; also can avoid the uncertainty of the risk of accidents at the company operation.

"See today's turbulent fate of the company rotation, and how to adapt to a rapidly changing society, Huawei really can not find any good way, the CEO of the rotating system is not a good way, it is the test of time." Ren said.

Single threshold solar cells has fundamental limitations

April 25 [Wed], 2012, 11:50
Photochemical conversion, two low-energy red photons battery combined with the formation of a yellow high-energy photons, which can be captured, and then into electronic.

Low-cost solar cells suitable for use as roof panels, can be achieved record-breaking 40% efficiency, this is because of an early breakthrough, University of Sydney (the University of Sydney) made by the researchers and his German partner.

With the support of the Australian Solar Institute (Australian Solar Institute), Professor of Chemistry, University of Sydney School of Tim (Tim Schmidt), Schmidt, hand in the Helmholtz materials and energy (of Helmholtz Centre for Materials, and Energy), has developed a "solar cells turbine turbocharger (the turbo for solar cells), known as photochemical conversion (photochemical upconversion), the energy normally lost in the solar cell into electricity.

This finding has been published in the journal of the Energy and Environmental Science (Energy & Environmental Science).

Professor Tim Schmidt said that this process of frequency conversion technology, the availability of this part of the solar spectrum, is not currently solar cells, which do not need big-budget re-development of solar cells.

Professor Schmidt said: "We can improve efficiency, just need to make two low-energy red photons in the combination of battery, the formation of a yellow high-energy photons, which can capture the light, and then into electricity."

"We now have a performance benchmark can be used for frequency conversion of solar cells we need to improve several times, but the path is clear."

Mark, Executive Director of the Australian Solar Institute (Australian Solar Institute) extension Dyer (Mark Twidell), said that this is an excellent example of successful cooperation, the cooperation between Australia and Germany is the leading solar researchers.

"In short, Australia and Germany, can accelerate the pace of commercialization of solar technology, reduce the cost of solar power," said Mr. extension Lauderdale.

"This is why the Australian Solar Institute (Australian Solar Institute) to support the cooperation between the two countries, they have a joint solar energy research and development projects in Australia - Germany (Australia-Germany Collaborative Solar, Research, and Development Program).

Abstract: single threshold solar cells has fundamental limitations because they only use more than a certain energy of the photon. Photons below the threshold, the re-radiation of this energy, the formation of a shorter wavelength, so that can improve the efficiency of these devices, we report that can improve the light harvesting efficiency of hydrogenated amorphous silicon (a-Si: H: hydrogenated amorphous silicon) thin-film solar cells, this is because the back of the inverter, relying on organic molecules sensitized triplet - triplet - annihilation (triplet-triplet-annihilation). low-energy light in the 600-750 nm range, can be converted to 550-600 nm light, this non-coherent photochemical process. peak efficiency improve (1.0 ± 0.2)%, equivalent to 720 nanometer measurement of irradiation (48 ± 3) sunlight (AM1.5,). We discuss these ways, the research to adapt to the photochemical frequency conversion for a single threshold devices. "

First batch of six electric vehicles will be used for residential

April 25 [Wed], 2012, 11:49
April 21, Stone City, the urban management department to carry out the recycling of used batteries and build a green home "and the 43 Earth Day campaign, according to statistics, on-site recycling of used batteries more than 400 kilograms more than 2000 copies for publicity. The reporter was informed that after this event, Shijiazhuang City, will be the first put into use specifically for the recycling of used batteries of electric cars.

Reporters on the scene saw specifically for the recycling of used batteries of electric cars and electric vehicles took a fancy to no difference, but it either side of two recycling bins installed in the rear frame and orange flashing lights the difference.

According to the relevant person in charge, do not look at the two recycling bins, but can accommodate about 20 kilograms of used batteries. Transparent admission in the box, placed between two recycling bins will be placed on water and wipes, such as recycling staff at the recycling bins (barrel) for cleaning. According to reports, the first batch of six electric vehicles will be used for residential, public places, as well as business-site recycling of used batteries.

Urban waste batteries produced annually by more than 1000 tons, the city is now installed more than 15,000 wall-mounted waste battery recycling boxes, and over 1000 vertical waste battery recycling bins, and the formation of a professional recovery team, recovery of personnel on a regular basis-site recycling of waste battery. "According to the introduction of the urban Management Committee is responsible for urban waste battery recycling sanitation Department official, at present, the city has formed a relatively complete waste battery recycling network, and can basically meet the recovery needs of the capital of the public.

Same time, through this event will further publicize the hazards of waste batteries, so that more people actively involved in waste battery recycling activities, and guide people to consciously develop a healthy, civilized, friendly lifestyle. Moreover, the public, if the 15 kg and above, used batteries, and can call the City Sanitation Department recycling of used batteries electric 83,830,174, and the recovery will be free to door recycling.

Crystalline silicon solar cells to more than 10 cm square silicon modules

April 25 [Wed], 2012, 11:48
From the point of view to improve solar cell performance required three technical elements, the CIS can be said to meet all conditions. Comparison of the use of other materials, solar cells and CIS solar cells, use the CIS solar cells that use other materials differ from it? CIS semiconductor can be said to be the most balanced of the material in the solar cell material.

"Low cost to produce one square meters of thin film silicon. However, due to the low conversion efficiency, to achieve the same power and CIS need to double the area of ??solar cell manufacturing the most energy consumption is glass, followed by aluminum framework, because the most energy consumption the glass doubling the manufacture of aluminum framework must also be increased, so the thin-film silicon is not worth the cost. "

To compare the results with the organic dye-sensitized? And thin-film silicon, because of the low conversion efficiency in the manufacturing of the product reached the practical level, the high total cost of production because the electrolyte solution, it is not possible to ensure stability, and durability, but if able to achieve a number of innovative improvements, this battery is also promising. "

So, compared to the same compound class "Cadmium (Cd) Te (Te) of the CIS thin film solar cells is how?

"A reference to cadmium, estimated that most people think of toxicity., Tellurium is a toxic substance. The actual structure of the CdTe solar cell is in the form of CdS / CdTe, the use of cadmium (Cd) more. Although studies have reported that the toxicity of the compound CdTe is lower than the toxicity of these two metals, but set to scrap all aspects of the estimated need for strict regulation., cadmium and tellurium are rare metals, should be a lot of popularity, material procurement will become very significant issue. "

As a result, the CIS's biggest rival really is crystalline silicon.

Have already said, use the CIS can not only reduce battery thickness, and material and energy costs are also reduced accordingly. On the other hand, the conversion efficiency of less than crystalline silicon has been the weakness of the CIS. Minister Li Tanigawa said with confidence: "However, now the CIS in the conversion efficiency of crystalline silicon is almost the same in the near future, within a few years people will realize that CIS is the highest conversion efficiency of solar cells."
"From the point of view of the solar cells on the market, the highest conversion efficiency of polycrystalline silicon is just approaching 18%, but the occasion of modular, efficiency will be reduced by 1 to 2 percentage points, the actual efficiency is estimated that between 15 to 16 percent. CIS solar cells dead zone in the state of 30cm square with all elements of the module conversion efficiency has reached 17.2%.

Thus, in recent years has been regarded as the weakness of the CIS solar cell conversion efficiency has been increased to match the degree of crystalline silicon.

CIS solar cell energy conversion efficiency. March 2011 the Atsugi Survey Center, Solar Frontier CIS thin film solar cells to sub-modules of 30cm square openings of area (including the area of ??the gap between the panel and other dead zone) to achieve the world's highest energy conversion efficiency of 17.20%.

CIS solar cells in the actual generation advantage

Conversion efficiency to be given full play the strength of the top CIS thin film solar cells in the actual utilization of solar power generation. There are validation results show that the "CIS solar cells almost throughout the year than other types of solar cell generating capacity". The final CIS solar cells, crystalline silicon solar cells a year, more than power generation by approximately 8%.

Are the result of such a gap, Li Tanigawa, explained: "One reason is the light effect. This is particularly reflected in the Company's CIS solar cells, the increase in conversion efficiency after irradiation sunlight, therefore, from the receipt of feedback, the output power than the factory supplied about 5 ~ 10% higher. "just like by the light while the growth of the output power rises. Moreover, under the actual conditions of use, when assembled into solar panels is actually put into use, but also shows the advantages of CIS solar cells.

"First of all can cite 'not afraid of the shadow of the CIS solar cell'." Crystalline silicon solar cells in series from a few centimeters to more than 10 cm square silicon modules. If one was shade shelter, or due to dirty power generation, the series circuit is open circuit, resulting in the entire panel to stop power generation.

CIS solar cells are arranged in a rectangular panel of less than 1.7 square meters of the width of several millimeters long and thin strip module, even if the shadow block, or part of the dirty, nor does it appear the phenomenon of paralysis of the entire module. Therefore, the series circuit will not disconnect the power generation can also be normal.


As a result, part of the panel by block, the CIS solar cells, crystalline silicon solar cells in the power generation capacity will make a big difference. Moreover, solar cells, the higher the temperature the lower nature of the power generation capacity. Therefore, the generating capacity of solar panels with solar cells, whether high temperature are closely related.

Temperature coefficient of the compound class more than crystalline silicon. In other words, even if the sunlight, the temperature rise, compared with crystalline silicon solar cells, CIS solar cell power generation does not have too much drop. "Not afraid of shadow by the light increased power generation efficiency, high temperature. These three conditions have created a good practical power generation capacity of the CIS solar cell.

However, being so excellent, why the manufacture and sale of CIS solar cells Solar Frontier, a? "The answer to this question with us why 20 years ago, began to study, but proceed to launch the CIS solar cell product that is the reason a few years ago."
"Stable and a large number of manufacturing large-area CIS solar cells is technically very difficult. In order to achieve stable mass production, the past 20 years has been conducting research and development, constantly honing technology. Our strength lies in the process development and device development. This is significant, "tells the remarks, Li Tanigawa in the eyes of the Minister of flashing a confident light.
