Ultracapacitors Key Facts & Benefits

Ultracapacitors, or supercapacitors as they are also
known, are an energy storage technology that
offers high power density, almost instant charging and discharging, lifetimes of 15+ years, and extreme reliability even in harsh conditions.
Fast energy storage, such as ultracapacitors, is increasingly important for the electrification of the largest industries in the world. Ultracapacitors help save energy and decrease emissions in automotive, transportation, grid, and industrial applications.
Skeleton-Ultracapacitor-Manufacturing
Our products
  • Very long lifetimes of more than 1 million charge cycles
  • A wide range of operating temperatures, from -40°C to +65°C
  • 30% more efficient than batteries
  • Zero maintenance
  • Up to 60 times the power density achieved by batteries
  • No harmful chemicals or toxic metals, easy recycling
