Research into slowing lithium degradation can extend Battery life by 30%
Research into slowing lithium degradation can extend Battery life by 30% February 2, 2022 by Jennifer Huber The massive scale-up of batteries is essential to a successful transition. That will be made much easier if the lifetime of existing lithium batteries is greatly extended. With each charge-discharge cycle, the batteries accumulate tiny islands of inactive lithium that are cut off from the electrodes, decreasing the battery’s capacity to store charge. Jennifer Huber at the SLAC National Accelerator Laboratory explains how new research is showing a way to bring that “dead” lithium back to life. The battery’s degradation can thus be slowed, increasing its lifetime by nearly 30% . It essentially requires adding a fast, high-current discharging step right after the battery charges . If proven with commercial batteries, this discovery could increase the mileage per charge for EVs or reduce the size of the battery pack , says Huber. Others, from grid storage innovators to el
