Samsung’s 900Wh/L solid-state battery could open up EV possibilities

Fri, 03/13/2020 - 14:17 -- Paul Crompton

Samsung has revealed a prototype solid-state battery that boasts an energy density up to 900Wh/L at around 50% smaller by volume than a conventional lithium-ion battery.

The prototype pouch cell would enable an EV to travel up to 800km on a single charge, and features a cycle life of more than 1,000 charges.
