Notes to Editors:

CAP-XX is a world leader in the design and manufacture of thin form supercapacitors and energy management systems, predominantly for portable electronic devices.

The unique feature of CAP-XX's supercapacitors is their ability to store high volumes of energy and output high power levels within a thin form design. These attributes will be critical for the next generation of high volume, power-hungry portable electronic devices, including mobile phones.

Portable devices are one of the fastest growing segments of the electronics market and provide the greatest opportunities for CAP-XX's products. CAP-XX's products are already an established enabling technology for the current generation of wireless devices and portable devices.
