Next generation supercapacitors for energy storage

The need

The increasing electrification of a wide range of industries creates a demand for lightweight, cost-effective and powerful energy storage systems. The main industries requiring such solutions are the automotive, transportation, heavy industrial equipment and power grid industries.

The solution

Skeleton’s supercapacitors stand out from others of their kind. Patented “curved graphene” holds significant advantages, but there are also major benefits offered by the cells. No other product on the market has as high power and energy density as Skeleton’s supercapacitor cells, the building blocks for supercapacitor modules and energy storage systems.

The value proposition

High energy density.
High power density.
Low internal resistance means high efficiency and less need for cooling.
Reliability and long lifetime.
