In recent years, lead-acid battery technology continues to develop, the product has matured. Start gradually the battery structure optimization and upgrading, maintenance-free batteries are widely used, is still an important power supply unit of the military, civilian transportation equipment, China has become the world's major car-producing countries play an important supporting role. VRLA batteries, gel batteries as backup power, the core component of the large reserves of power, its production has become an important basic industry in national economic development. Promising lead-acid battery industry.
Repeated use of the main raw material of lead-acid batteries - lead recyclable, as long as the introduction of relevant industrial policy of the recycling of used batteries properly guide the market, we can effectively solve the shortage of China's nonferrous metal, lead contamination and other resources, environment, many problems. Therefore, the correct understanding of the statusreplacement JKVC5
of the battery industry, identify trends, to effectively solve its own problems in the recycling of resources and building a conservation-minded society, is an effective way to the scientific development of the national economy.
China's lead-acid battery industry status quo
Since joining the WTO, with the increase of investment driven by national industry and international battery manufacturers in China, the Chinese lead-acid battery industry development faster annual growth rate of more than 30%. With the increasing international market demand, China has also become one of the world's largest exporter of lead acid batteries. China's lead-acid battery technology is not obvious, and the gap between international standards and car batteries at the international advanced level, with power for electric bicycle battery technology approach international advanced level.
After 20 years of development, maintenance-free sealed battery technology and progress made great achievements in the lead-acid batteries are widely used not only in traditional areas such as transportation, military defense, and is widely used solar photovoltaic, wind power, communication power , electrical power distribution systems, railways, ship communications, starting, lighting, power supply, UPS power supply. Technological progress to promote the rapid development of the battery industry, making it one of the new sunrise industry. However, due to the substantial increase of the prices of major raw materials of lead-acid batteries - lead in the second half of 2004, and continued to maintain the operation of the high price of lead-acid battery industry profits declining.
In recent years, with changes in market demand, production methods and processes of lead-acid batteries continue to improve, the manufacturing level rising, battery energy density, cycle life, performance, consistency, security and environmental continuous improvement. With the development of electric bicycle battery power supply, high-temperature curing technology has developed rapidly. Is generally believed that the high temperature curing can improve battery life in recent years and negative additive and ratio also accumulated a Greater gesep.com amount of parameters, and identify some regular experience. Domestic other advanced technologies such as spiral wound batteries, bipolar, thin plates, etc. are still in the research stage, there is no mass production.
The report from our patented technology, the battery industry in recent years, the overall technology development line of defense is the battery structure improvement and battery model development. Thin plate of foreign patents mainly involve cash bipolar lead batteries, sealed battery module structure, and colloid electrolyte lead battery. Therefore, our patented technology with foreign countries there is a certain gap.
Environmental status quo and the problems of lead-acid battery industry
After years of construction and development of lead-acid battery industry in China has basically formed the system and showed a trend of rapid development, environmental problems have made breakthrough progress, present, China's lead fume and dust, sulfuric acid mist and water treatment methods and technology ripe, the major and medium-sized lead-acid battery manufacturers continue to increase the technological transformation efforts, updating process equipment, and generally environmentally friendly high-efficiency cartridge dust collector instead of electrostatic precipitators, wet scrubber to clean smoke lead, using the turbulent type mist purification tower sulfuric acid mist to absorb processing, response to the lead-acid-containing wastewater flocculation treatment to eliminate or reduce the impact of pollutants on the environment, technically, the production operating environment continues to improve, most large and medium-sized manufacturing enterprises to achieve cleaner production. in part through the National Environmental System Certification.
However, due to several reasons, the pollution problem of the battery production process has not been solved, in particular, is a serious pollution problem in a large number of some medium-sized and small enterprises of the production process: many manufacturers, small scale, and are more polluting, quality varies missing, do not have the environmental conditions of workshops factory herd, about a quarter of enterprises without the approval of the environmental unauthorized site construction, pollution control facilities is not complete, the production is not in the strict environmental protection measures and industrial safety and health conditions, caused harm to the operator and the ecological environment. Production license system is not strict clean production, environmental protection facilities standard mark. Although China since 2005, the production license system, but there are some problems in the approval and implementation, and did not really promote the production enterprises to achieve cleaner production, many manufacturers are not up to converted to legalization (currently issuing enterprise has reached 930 home), resulting in serious environmental problems. Related to environmental protection law, there are still many imperfect and unsatisfactory. Comparable to the amount of the fine for polluting enterprises, environmental protection departments is limited, and can not be caused by industrial pollution and social losses. In addition, the state is not specified, the protection of large, medium-sized battery manufacturer's policy, and local environmental protection departments also belong to the management of a small battery manufacturers only paid attention to the supervision of large and medium-sized enterprises, resulting in large and medium-sized enterprises sewage charges and monitoring costs, the "three simultaneous" evaluation fees, and a heavy burden.
The key initiatives to solve the environmental problem is the full implementation of a battery recycling policy
China is actively implementing a circular economy, 90 percent of the waste batteries can be recycled, but China's industrial policy is not to waste battery recycling is a good development space, resulting in a long-term problem in China's battery development bottleneck. China there is no statutory specification of a used lead-acid battery recycling management, the country did not establish a professional waste lead-acid battery recycling companies, without a professional Secondary Lead business or battery enterprises to establish a nationwide recycling network and regional recycling network, the whole recovery work in the disordered state of the decentralized management of waste lead-acid battery recovery rate is not high. Lead recovery problems among the non-standard enterprise, rectification is imperative to strengthen the management, the relevant state departments should introduce policies to ban small coal mines, smelting, banned a small scrap of lead recycling business. Also introduced policies to encourage and support large-scale battery manufacturers for recycling of used batteries. Restricting China's Secondary Lead the development of the industry factors: first, the heavy burden on the cost of environmental protection equipment. Enterprises with advanced technology, and environmental well-equipped business efficiency is no match for technological backwardness, serious pollution of the township, "lead smelting. Second, the supervision is not enough. No business license is also Lead production, rectification palliatives, were closed to the lead smelting wind over the resurgence. Third, industrial policy is not conducive to the development of informal enterprises. Taxes too heavy also weakened the ability of enterprises to increase environmental protection and management of large Secondary Lead.
China's lead-acid battery industry development trend
The hundred-year-old lead-acid batteries due to cheap materials, simple technology, the technology is mature, self-discharge is low, and requirements for maintenance-free features in the next few decades will still be in the market dominant, although the starter. power battery market space may be the turning point, will remain dominant in the recent national industrial development, medium-term will have a place in the long run, without the high weight-specific energy use field will continue to exist. Currently, its main application areas such as automotive, motorcycle, standby power use in a substantial increase, but also in new fields of application such as electric bikes, the tour bus with the development of valve-regulated battery technology development to meet the power needs of high-tech equipment such as UPS, electric power and communications. Lead-acid battery technology continues to progress, making electric bikes industry tremendous development, and contributed to the pollution and reduce fuel cars and fuel motorcycle. Maintenance-free technology, the development of the pull-grid technology to meet the demand for rapid development of automobile industry. It can be said that the technological progress of the lead-acid batteries in these applications to make a real contribution to enhance national competitiveness.
Demand for small mobile power supply, power tools, electric bicycles and other industry stimulated the rapid growth of the battery industry. Configured in the electric bicycle battery most of the VRLA battery, after a performance improvement, than a breakthrough in energy and cycle life, but so far, there are still in the high rate is not high enough energy, deep cycle life is not long enough shortcomings, largely affected the rapid growth of the electric bike industry.
Electric bicycles as a means of transport in less developed countries in recent years has developed rapidly, especially in China. Development by 290 000 in 2000 to 12.09 million in 2005, average annual growth rate of 174%. Can be expected in the future for a long period of time, the electric moped battery products will flourish. China's electric bicycle battery power for more than 95% of lead-acid batteries. Electric bike battery market capacity in 2006 have a 40-50 billion by 2015, China's electric car output will reach 100 billion yuan, of which 16 billion yuan supporting the battery. Replace the battery of the secondary market amounted to 48 billion yuan, which is a huge market.
