Summary

The Redwire All Solid-State Battery (ASSB) Pack is a drop-in replacement for spacecraft power. The ASSB Pack offers a configurable, high performance power cell with mission safety assurance. The ASSB Pack provides high energy density and volumetric efficiency, and is safer and less reactive than traditional Li-ion liquid electrolyte technology.

Redwire has a partnership with a US-supplier that maintains a production line nearby in Colorado. With expertise in solar arrays, batteries, and mission systems, Redwire supplies power systems, from components up to complete EPS'.

Key benefits of the ASSB Pack include:

  • Low Mass - increased energy density of solid state batteries enables low mass battery systems
  • Safety - Eliminates flammable liquid electrolyte creating a safer battery system
  • Security - MWh production line in Colorado, capable of serving US space & defense markets
  • Configurable - 20Ah building block is modular, capable of being paralleled together for large systems( smaller or custom packs are possible)
  • Flight Heritage - funded flight demonstration of ASSB cell technology is targeted to fly in 2024.

Applications of the ASSB Pack include:

  • Earth Orbit Missions (LEO, GEO, HEO, MEO)
  • Lunar Missions
  • SmallSat Missions
  • CubeSat Missions
  • Spaceflight Missions
  • Space Vehicle Electrical Power System
  • Customized Payload Power Solutions
