Knowing how the ions are distributed in a battery

A group at the University of California San Diego is also working to improve battery charging, with the ultimate goal of designing 42T5263 high quality and charging systems for electric vehicles that are based on a better understanding of what physically happens inside of a lithium-ion battery over time. A team of engineers led by Miroslav Krstic and Scott Moura recently created a sophisticated mathematical model of the location of the lithium ions within a battery as it charges and discharges.

Knowing how the ions are distributed in a battery over time could open the door for researchers to find the optimal rates for charging and discharging batteries. Consequently, they could design lighter batteries that charge faster. Usual methods of monitoring batteries, such as measuring current and voltage, are less accurate and can lead to batteries that are overbuilt and oversized for the job. However, the team of engineers estimate that this new technique could reduce the cost of lithium-ion 51J0497 high quality by as much as 25 percent and enable them to charge in as little as half of the time.

Both of these models require additional testing in real word situations to see how they compare to existing techniques, but they are important steps toward making electric vehicles more appealing to drivers who are used to refueling quickly when the tank is getting low. They are also likely to be useful for applications beyond electric vehicles ― and could form the basis for better battery monitoring and recharging systems in future generations of battery powered devices.
