Many owners of electric vehicles worry about how effective their battery will be in very cold weather. Now a new battery chemistry may have solved that problem.
In current lithium-ion batteries, the main problem lies in the liquid electrolyte. This key battery component transfers charge-carrying particles called ions between the battery's two electrodes, causing the battery to charge and discharge. But the liquid begins to freeze at sub-zero temperatures. This condition severely limits the effectiveness of charging electric vehicles in cold regions and seasons.
