Mercedes has begun testing an EQS equipped with a solid state battery. It provides 25% more range than a lithium-ion battery of the same size and weight. Solid state batteries offer higher energy densities and safety benefits over traditional batteries.

The race for the “holy grail” of EV batteries is heating up. Mercedes-Benz is now testing EVs with solid-state

Solid-state batteries are expected to be the future of EVs, but they have proven difficult to develop and manufacture on anything close to a commercial scale. Mercedes appears to be moving ahead of the curve,

With the same battery size and same weight, the solid-state chemistry is expected to deliver 25% more range on the prototype EQS.
