What Happened
Rimac Technology and battery developer ProLogium presented a conceptual cell-to-pack solid-state battery platform at the 2026 Paris Motor Show, laying out development benchmarks through the end of the decade.
Initial pouch cell-to-pack concept mockup showcased at Paris Motor Show
Functional battery segment display scheduled for CES 2027
Assembly and bench testing of complete working battery pack
Full-scale on-road vehicle trials in automotive test environments
Expanding on preliminary agreements initiated at the IAA Mobility exhibition, the venture combines ProLogium's lithium-ceramic solid cells with Rimac Technology's proprietary enclosure structures, pressure mitigation, and thermal control circuits. Eliminating internal intermediate modules aims to lower overall pack weight while expanding volumetric packaging efficiency.
“Demonstrating this cell-to-pack platform with Rimac Technology shows how solid-state cell integration can eliminate traditional module structures and optimize energy density for automotive applications.”
Project engineering specifies an active hardware segment debut at CES 2027 to validate swelling mitigation and heat dissipation, followed by a fully operational pack milestone late next year before real-world automotive evaluation in late 2028.
Why this matters
Transitioning solid-state cells from laboratory benches into functional cell-to-pack hardware is essential for commercial viability in high-performance electric vehicles. Rimac Technology's mechanical and thermal integration expertise tackles cell breathing and pressure constraints inherent to ceramic solid electrolytes.
