BMW, Samsung join hands to back solid-state battery to double EV range

BMW, Samsung SDI, and Solid Power have formed a strategic partnership to advance all-solid-state battery (ASSB) technology for electric vehicles (EVs). Building on BMW and Solid Power’s collaboration since 2022, Samsung SDI brings its expertise in large-scale cell manufacturing and materials engineering to produce ASSB cells using Solid Power’s sulfide-based solid electrolyte. BMW will focus on battery pack and module design. This collaboration aims to develop safer, higher-performance batteries with improved energy efficiency, marking a significant step toward commercial-scale production of ASSBs. Samsung SDI has already launched a pilot production line in South Korea and begun producing prototype solid-state batteries, which have been delivered to customers for evaluation. Meanwhile, BMW conducted successful on-road tests of Solid Power’s ASSB cells in a modified i7 sedan, targeting the introduction of these batteries in production EVs by around 2030. ASSBs promise to double EV driving range and enable faster charging, addressing key limitations of current lithium-ion batteries
