Problem
Conventional lithium‑ion batteries limit electric vehicle range, increase system weight, and require long charging times, while safety concerns and high material costs hinder broader adoption in defense, aerospace, and mobility applications.
Solution
Sion Power’s Licerion® platform delivers lithium‑metal cells that provide up to twice the energy density of standard lithium‑ion packs, enabling lighter battery packs and longer range. The technology combines a proprietary vapor‑deposited lithium anode, an optimized electrolyte, and patented compression‑based dendrite‑resistance to ensure safe, fast charging operation. Cells achieve specific energy above 433 Wh/kg and energy density over 1,000 Wh/L, with power output up to 4,000 W/kg and a cycle life exceeding 800 cycles. The platform is cathode‑agnostic and certified to UN 38.3 safety standards, allowing integration into demanding defense, aerospace, and automotive systems. Pilot‑scale production and extensive testing infrastructure support rapid qualification and scaling for OEM partners.
Target Audience
Primary customers are defense and aerospace OEMs, electric‑vehicle manufacturers, and system integrators seeking high‑energy, lightweight battery solutions for performance‑critical platforms.
