Charging lithium-ion cells at different rates boosts the lifetimes of battery packs for electric vehicles, Stanford study finds

New modeling of how lithium-ion cells in a pack degrade show a way to tailor charging to each cell's capacity so EV batteries can handle more charge cycles and stave off failure. Simulations by Stanford professor and senior study author, Simona Onori, suggest batteries managed with the new technology could handle at least 20% more charge-discharge cycles even with frequent fast charging.

California's move to phase out gas-powered cars could spark battery innovations

By 2035, California will ban sales of new gasoline powered cars and light trucks. Yi Cui, professor, materials science and engineering and director, Precourt Institute for Energy predicts the broad adoption of EVs will force a revolution in battery design. The need for fast charging, he says, “will definitely provide opportunities for new battery chemistries to emerge.” By using new materials for electrodes or charge-carrying ions, he and others have already come up with promising candidates.
