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

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.

While the solid state battery pack was developed and patented by Mercedes-Benz in collaboration with Mercedes AMG High Performance Powertrains (HPP), the battery cells were developed by Factorial Energy using a novel floating cell carrier.

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.

Lab testing of the EQS test vehicle shows that the solid-state battery provides up to 25% additional electric range. The post Road tests start on solid-state EV battery developed by Mercedes AMG and F1 engineers appeared first on The Manual.

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?

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,
