Ionic liquid lithium-ion battery for extreme environments (vacuum, high-temperature, cryogenic)

Non-flammable, non-volatile lithium-ion battery using ionic liquid electrolyte that operates in vacuum (space-proven), at high temperature, and sub-zero conditions without swelling or ignition.

Problem solved

Conventional Li-ion batteries with organic-solvent electrolytes are flammable, volatile, swell in vacuum, freeze at low temperature, and fail at high temperature. This limits applications in space, aviation, desert solar, and medical devices. The ionic liquid electrolyte (molten salt, room-temperature liquid) eliminates volatility and flammability while maintaining wide-temperature operation.

Application contexts

  • Space satellite batteries
  • Aerospace and aviation batteries
  • Medical device power (implantable, surgical)
  • Desert/solar farm energy storage
  • Industrial IoT sensors in extreme environments

Technical principle

Replaces conventional organic solvent electrolyte (e.g., LiPF6 in EC/DMC) with an ionic liquid (room-temperature molten salt composed solely of cations and anions). The ionic liquid has negligible vapor pressure (does not evaporate or outgas), is non-flammable, and maintains ion conductivity across a wide temperature range.

Typical use cases

  • Spacecraft and satellite battery systems requiring zero outgassing
  • Medical device batteries requiring non-flammable chemistry
  • Solar farm energy storage in desert/tropical climates
