Our Ultracapacitor technology has the following benefits for the aerospace industry:


  • Ability to operate in extreme cold and hot environments
    • FastCAP EE Ultracapacitor modules operates safely at 150°C
    • FastCAP Aerospace Ultracapacitors operates at temperature extremes -70°C or 200°C
  • Ruggedness
    • Ability to withstand high shock and vibration conditions: up to 1000 Gpeak shock and 60 Grms vibration. Traditional ultracaps do not have these capabilities and tend to be fragile in extreme environments
  • Reliability and Safety
    • Safe nature of the ionic liquid based electrolytes. Ionic liquids are non-volatile (even in vacuum) and non-flammable. Lithium free
    • Consistent performance over time due to the electrostatic energy storage mechanism as opposed to electrochemical mechanism of batteries, which results in performance degradation over time
  • Significant Weight and Volume reduction
    • Volume and weight reduction due to high power density, compared to traditional batteries and ultracaps.
    • These devices can replace traditional batteries for high power applications or be a complementary energy storage system in a hybrid configuration with high energy density batteries
  • Long Life
    • The proposed device can be charged and discharged over 1,000,000 times, greatly improving system reliability and cost savings over time
  • Efficiency and High Power
    • Offer high power density during surges and the ability to absorb high power for recharging
  • Low Maintenance, Cost Reduction
    • Rugged, reliable and easy-to-maintain design. No thermal management required prior and during missions.


A comparison between the ultracap proposed in this program and the state of the art of commercially available ultracaps and Li-Ion batteries is provided in the table below:
