What are ultracapacitors?

What are ultracapacitors?

Ultracapacitors or supercapacitors are an energy storage technology that offers high power density, almost instant charging and discharging, high reliability, extreme temperature tolerance, and lifetimes of more than 1,000,000 charge-discharge cycles.

 

Ultracapacitors have been in development for decades, but the biggest development steps have happened only in the past 15 years, driven by advances in nanomaterials with Skeleton's Curved Graphene being a prime example of a breakthrough technology.

Ultracapacitors are now delivering significant economic benefits in the form of energy and fuel savings across a wide range of markets including automotive, grid and renewable energy, transportation, and industrial applications.
