ProLogium and Rimac Unveil Lighter Solid-State Battery Design, Target 2028 Road Tests
Taiwan's ProLogium and Croatia's Rimac showed a new solid-state battery design at the Paris Motor Show that replaces heavy casings with flat, flexible cell packs.
In electric vehicles, the battery does more than determine range. It also shapes the car's total weight and its design. As batteries get heavier, the load the vehicle carries increases. Manufacturers are therefore looking for ways to travel farther with less weight.
Taiwanese energy company ProLogium and Croatia-based Rimac presented a new battery design aimed at this goal at the Paris Motor Show. The system is currently on display as a design mockup. Its key feature is how the cells are installed in the vehicle, which takes a different approach from traditional battery packs.
Flexible packs instead of heavy casings
In the next generation of solid-state batteries, cells are placed directly into the battery system in flat, flexible packs rather than being grouped inside heavy metal casings. This structure gives automakers two options: a longer range at the same weight, or a lighter vehicle with the same range.
Timeline points to late 2028
According to the plan announced by the companies, the design mockup is targeted to become a working system in early 2027. Toward the end of the same year, the companies plan to produce a battery ready for integration into vehicles.
After laboratory and safety testing is complete, road tests on real vehicles are expected to begin toward the end of 2028. As a result, the design is still several years away from appearing on the road.
The report did not say which manufacturer or model will use the battery, or provide concrete figures for range or weight gains. For now, what has been presented is the idea that pack design in solid-state batteries could change the balance between range and weight, along with its timeline.
