Mercedes is developing solid-state batteries with the aim of having the technology ready by the end of the decade.

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,

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.

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

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

Mercedes-Benz and American battery start-up Factorial Energy have developed a prototype EQS equipped with a solid-state battery. The companies claim it's the "world's first solid-state battery vehicle from a global OEM." It’s already out on the road doing test runs.

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.

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,
