Rimac unveils solid-state battery pack platform at IAA Mobility 2025

Rimac Technology revealed a new battery pack platform that uses only solid-state batteries at IAA Mobility 2025 in Munich. The platform was developed in collaboration with ProLogium and Mitsubishi Chemical Group and is claimed to be lighter, safer and more energy-dense than conventional EV battery systems.

Key details

• Partners: ProLogium (solid-state cells) and Mitsubishi Chemical (advanced materials)
• Claims: Reduced weight, improved safety, higher energy density
• Readiness: Rimac described the platform as production-ready at the show but did not provide a customer availability timeline.

Context

Solid-state batteries are seen as a major potential leap for EV efficiency and cost. European R&D groups and industry partners have reported encouraging technical results, but commercial deployment has been slower than initial expectations. For example, Nissan has targeted 2028 for a production EV using solid-state cells.

Rimac showcased this platform alongside new composite and hybrid battery developments and advanced powertrain hardware at IAA Mobility 2025.
