The emerging battery technology promises longer range, faster charge speeds, and is production feasible. Mercedes-Benz is testing a prototype EQS electric sedan fitted with a semi-solid-state battery pack co-developed with its Formula 1 powertrain subsidiary,

German carmaker Mercedes-Benz claims to have become the first carmaker in the world to drive a car powered by a lithium-metal solid-state battery

Mercedes has modified an EQS to test its prototype lithium-metal solid-state battery and the results are already looking really promising, taking range from 488 to a theoretical 621 miles. The succinctly named Mercedes-Benz Centre for Competence for Battery Systems is working with battery cell manufacturer Factorial and the AMG High Performance Powertrain guys (yep,

Mercedes tests motorsport solid-state battery in a Mercedes-Benz EQS on the road. With the same weight and space requirement, the range increases to 1000 km.

The initiative marks the first road test of a lithium-metal solid-state battery integrated into a passenger vehicle.

A version of the Mercedes EQS is testing solid-state cells from Factorial teasing a 25% boost in energy density. Will it really deliver the 621-mile target?

The German automaker has unveiled that a prototype EQS, equipped with a solid-state battery developed in collaboration with US startup Factorial Energy, has begun real-world testi

The solid-state battery race has heated up, with Mercedes bringing on a road-going prototype in the form of the EQS sedan.

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,
