Product catalog summary
General Description:
  • The super capacitor is a new energy storage device that combines the benefits of traditional capacitors and batteries.
  • It offers a high power density ranging from 300W/kg to 5000W/kg, significantly higher than that of batteries.
  • Features high-current discharge capability with efficient energy conversion and minimal process loss.
  • Boasts a long cycle life, capable of 500,000 to 1 million deep charge and discharge cycles.
  • Fast charging capability, reaching over 95% of rated capacity within 10 seconds to 10 minutes.
  • Operates effectively in a wide temperature range from -40℃ to 70℃, suitable for harsh conditions.
  • Environmentally friendly with no harmful gas emissions or heavy metal pollution.
  • Maintenance-free with low leakage current and long voltage holding time, ensuring long-term storage.
