Solid-state lithium-ion batteries offer a variety of benefits over alternatives. However, when these devices are operated at the high capacities and charging-discharging rates that electric vehicles demand, lithium dendrites grow toward the cathode side, causing short circuits and a decay in capacity.
To address the issue, engineers at the University of Maryland have developed a new technology that could enable next-generation EVs to be less prone to battery fires while increasing energy storage. Their process stops dendrite formation.
