CAP-XX has also received awards from Electronic Design, EDN, Design News, the European Electronics Industry and the World Economic Forum.

Supercapacitors combine the energy-storage capability of batteries with the rapid charge and discharge times of conventional capacitors. They handle the large instantaneous power demands inherent in flash photos, playing audio and video, and wireless transmissions, enabling new functionality and extending battery life.

Utilizing breakthrough nanotechnology processes, CAP-XX supercapacitors are the smallest and thinnest available today for any given ESR and capacitance. They pack high energy and power densities into thin prismatic packages suitable for use in slim, portable electronic devices such as camera phones, PDAs, digital cameras and multimedia players.
