Mercedes-Benz and Factorial, a self-proclaimed industry leader in solid-state battery research, have announced their latest breakthrough in EV battery tech with a new 'Solstice' pack that promises to deliver an enormous range – by the end of the decade.
The next-generation solid-state battery (SSB) is said to offer an energy density of up to 450Wh/kg. That means it promises to be much more compact, lighter and safer than the current lithium-ion packs used in today's electric vehicles.
