Secondary and Primary Li-ion Batteries

Secondary and Primary Li-ion Batteries Based on Unique Ionic Liquid Electrolytes, with Very Wide Operating Temperature, Very Long Shelf Life, Non-Flammability, Radiation Resistance and High Capacity / Power

Unique secondary (rechargeable) and primary Li ion batteries with very wide operating temperature (-20°C to +55°C), 20-year shelf life, no self-discharge current during storage, high power (93 Wh/kg for fully packaged battery), voltages ranging from 3.7 V to 28 V, and resistance to radiation and acceleration (tens of g‘s). Based on specially developed ionic liquid electrolytes.

  • Use unique electrolyte based on patented ionic liquids.
  • Wide operating temperature, (-20°C to +55°C).
  • Non-flammable: Ionic liquid based electrolyte also yields non-flammability.
  • 20-year shelf life: Due to unique battery design and unique initial charging method, which together eliminate self-discharge entirely. Shelf-stored battery is activated within a minute.
  • Battery voltages from 3.7 V to 28 V.
  • Performance parameters of final 28 V battery, in metal housing:
    • Specific energy (power) at least 93 Wh/kg, at all temperatures within operating temperature range.
    • Energy density 75 Wh/L.
    • Capacity 3.3 Ah/kg.
  • Designed to endure flash X-Ray, low-dose X-ray and gamma-ray radiation in near-space/reentry/-low earth orbit (LEO), acceleration of tens of g‘s.
