Energy Storage

Calgon Carbon, a world leader in the innovative use of activated carbon, has developed advanced activated carbons for energy storage and continues to develop products offering improved electrochemical performance.

Our activated carbon products for energy storage are specifically designed for use in ultracapacitors, asymmetric devices and advanced batteries and offer a performance advantage to other products available today.


Activated carbon is the preferred electrode material in ultracapacitors, asymmetric batteries and a variety of advanced batteries because of the exceptionally high surface area and relatively high conductivity of the material. Calgon Carbon’s activated carbon products for energy storage were developed with high activity and high purity to deliver maximum electrochemical performance.

Calgon Carbon is a pioneer in the commercialization of advanced activated carbons for energy storage, with projects that focus on developing activated carbons for a broad range of ultracapacitor storage applications. Independent testing by one of the world’s largest ultracapacitor manufacturers demonstrates that Calgon Carbon’s products offer superior end-of-life and durability performance.

To continue to advanced the energy storage industry and to create a source of renewable green energy, Calgon Carbon is actively working on developing advanced activated carbons for ultracapacitor storage and other energy storage devices that are both technically and economically superior to the products available today.

Ultracapacitors – high capacitance energy storage devices. The storage mechanism for ultracapacitors is physical vs. a chemical reaction as with batteries.

Advanced Batteries – As the demands for energy storage devices become more rigorous, a variety of battery chemistries are being developed to provide higher energy densities and greater power output. The use of activated carbon provides additional performance advantages in asymmetric devices, advanced lead acid batteries and other battery technologies.
