With over two decades of research and development, Sion Power has created technology that significantly enhances the energy and cycle life of rechargeable lithium-metal batteries.


Licerion lithium metal cells in battery pack

Envision a world without constraints.

Demand for a lighter, higher-energy battery has been the driving force behind years of research and development by the team at Sion Power. The goal was to push the boundaries of energy storage technology to create the Licerion® rechargeable battery. Licerion batteries are setting a new standard for lithium batteries by offering the highest combination of energy density and specific energy available. Find out how Licerion batteries can give your application the freedom to go further.

High Performance

Big energy, small package

Big energy, small package

Batteries made using Licerion® rechargeable technology offer applications key performance advantages over other technologies. Lighter and smaller than a lithium-ion cell yet with increased energy storage, Licerion technology can enable longer missions and increased payloads.

Proprietary anode and electrolyte coupled with a high-energy cathode

Produced in-house, Sion Power has developed a patented Protected Lithium Anode (PLA), a key component that enables Licerion® batteries to store energy at levels unachievable by other battery technologies. Incorporating thin, chemically stable ceramic barriers, the Licerion PLA reduces parasitic reactions, minimizing weight while maximizing energy, cycle life, and safety. Additives in Sion Power’s proprietary electrolyte system further improves safety and extend cycle life. The result is a battery that offers the highest combination of energy density, specific energy, and cycle life available.
