Rimac Technology has introduced a new electric vehicle battery platform that exclusively uses solid-state cells. The company, a known supplier to high-performance automakers like Aston Martin and Koenigsegg and the maker of the Nevera hypercar, developed the product through collaborations with ProLogium and Mitsubishi Chemical Group.
Rimac claims its new solid-state battery design will lead to a lighter, safer, and more energy-dense power source for electric vehicles. The technology was unveiled alongside other new developments in composite and hybrid battery systems at the IAA Mobility 2025 event.
Solid-state batteries are widely seen as a major next step for EV technology. They replace the liquid or gel electrolyte found in current lithium-ion batteries with a solid material. This fundamental change is believed to offer significant advantages. A study from the European R&D organization Imec last year supported these claims, indicating the tech has the potential to greatly improve efficiency while simultaneously reducing manufacturing costs.
Despite the promising outlook, the path to commercializing solid-state batteries has been slow. While numerous automakers announced partnerships and development plans several years ago, the goal of putting EVs powered solely by this technology on the road remains distant. For example, Nissan has stated it aims to have its first all-solid-state battery EV ready by its 2028 fiscal year. Rimac did not provide a specific timeline for when its new battery platform might be available for customer vehicles.
