Specializes in solid-state lithium batteries using a proprietary polymer composite electrolyte and high-silicon anode. Achieves energy densities exceeding 450 Wh/kg, addresses thermal instability and safety limitations of conventional lithium-ion cells, and leverages scalable, adaptable manufacturing processes compatible with existing production lines to reduce costs and accelerate adoption.
Prototype solid-state battery cells produced on the A-Sample Line with capacities up to 80 Ah. Designed for electric vehicles (offering longer range and faster charging), stationary energy storage systems (providing reliable integration of renewable energy), and portable devices. Features include high energy density, improved safety, and enhanced durability.
In 2024 launched the A-Sample Line manufacturing plant, producing prototype solid-state cells up to 80 Ah and delivering first cells to major automotive and aviation partners. Plans to inaugurate a new R&D Center and prototype manufacturing line by the end of 2025, aiming for commercial readiness by 2027 with an annual capacity target of 10 GWh.
