Technology
The Standard in Lithium-Metal Batteries
Licerion®, Sion Power’s proprietary patented technology, is purpose-built to overcome the barriers that have held lithium-metal batteries back, delivering breakthrough energy density, lower system weight, and improved safety.
INDUSTRY
Drone & Defense
Sion Power offers the next generation of Licerion® primary battery solutions engineered for the demands of modern defense UAV operations.
Licerion cells replace the graphite anode used in conventional lithium-ion batteries with lithium metal. Using lithium in its metal form allows you to store more energy per unit of mass and per unit of volume than any other lithium-based chemistry available today — delivering energy density exceeding 500 Wh/kg, more than 50% beyond the best lithium-ion cells on the market, including those with advanced silicon anode enhancements.
Product overview
Licerion® Technology for Defense
Licerion® Strike™
Primary Cell — Single Discharge
Strike is engineered for high-rate, single-discharge applications. Its 6C discharge rate supports sustained high-power output through the full discharge curve — without thermal derating. The cell maintains performance integrity under the aggressive load profiles that terminal-phase and high-speed applications demand.
Licerion® Echo™
Rechargeable Cell
Echo is optimized for energy retention over extended discharge cycles. The rechargeable cell is designed to maximize usable capacity across long-duration profiles, with chemistry and cell architecture tuned for stable, low-fade performance across repeated charge and discharge cycles.
INDUSTRY
Electric Vehicle
Building the future of batteries in the sky and on the roads.
With more than 30 years of lithium battery development, Sion Power is trusted by top-tier partners and backed by 430+ patents. From our beginnings as a Brookhaven National Lab spin-off to today’s cutting-edge Licerion® platform, we’ve led the way in energy-dense, lightweight, and scalable battery solutions.
