Solid State Lithium Battery Cells

Solid Energies Inc. (SEI) is an industry-leading developer and manufacturer of solid-state Li-ion battery that has been funded since 2017 by DoD, DoE, NASA and California Energy Commission (CEC). Currently, SEI, through its subsidiary, Solid Master Battery (www.solidmasterbattery.com),  is launching the 1st generation solid-state battery cells products based on the well-established, high-performance semi-solid Li-ion technology.


1st Generation Solid-state Battery Cells 
Engineered for the most critical aerial and robotic missions, the SolidMaster solid-state battery cells, built on SEI's proven technology, empowers your UAVs, drones, and high-demand applications with unmatched power and inherent safety. Delivering a sustained 7C discharge rate for high-thrust operations, its advanced solid-state design eliminates flammable liquid electrolytes while providing superior energy density for extended range and reduced weight.

  • Longer Endurance: Superior energy density for extended flight times and mission range. With the same capacity, the cell products are 15%-30% lighter; and with the same weight/size, they are 15%-30% better in performance, as compared with the traditional technology.
  • Rapid Charging/discharging: Supports high-rate discharge (3C continuous, 7-10C peak) and fast charging rate (1-3C).
  • Much Enhanced Safety: Solid-state architecture eliminates the risk of leakage and thermal runaway, ensuring operational integrity.
  • Proven Durability: Rated for 500+ cycles, this military-grade power source is built for reliability in the most demanding environments.
