Sodium-Ion Batteries
CATL and Changan have unveiled the world’s first mass-produced sodium-ion EV, a 248-mile car that keeps most of its range at minus 40C, a potential turning point away from lithium.
CATL is chasing lithium-air batteries with a theoretical energy density of 12,000 Wh/kg, roughly that of petrol, a leap that could obliterate the range gap between EVs and combustion cars.
