Mercedes, Factorial unveil solid-state battery that can extend EV range by 80%

Mercedes-Benz is set to introduce new all-solid-state electric vehicle (EV) batteries developed in collaboration with Factorial Energy. This innovative battery technology, named Solstice, promises to extend the range of EVs by up to 80% and enhance safety while reducing costs. Factorial's solid-state batteries utilize a proprietary FEST (Factorial Electrolyte System Technology) platform, which has been in development for several years. The new batteries are designed to operate safely at high temperatures and eliminate the need for heavy cooling systems, contributing to lower overall vehicle weight and cost. With an energy density of 450 Wh/kg, these batteries aim to achieve over 600 miles of driving range while being 33% smaller than traditional lithium-ion batteries. Mercedes views this technology as a crucial element of its strategy to lead in EV battery development, with plans to launch these batteries by the end of the decade. The announcement follows similar developments by other automakers, including Toyota, which is also advancing solid-state battery technology to enhance domestic production capabilities in Japan.
