For immediate release

CAP-XX to Speak on Bridging the Power Gap between Energy-Harvesting Sources and Peak-Power Applications at Energy Harvesting &
Storage USA

Supercapacitors play energy-storage and peak-power-delivery roles

Sydney, Australia – October 30, 2009 – On November 4, Pierre Mars, vice president of applications engineering for CAP-XX Ltd (LSE:CPX), will present a technical paper on design strategies using a supercapacitor to overcome power limitations from energy-harvesting sources. Small solar cells, vibration transducers and RF harvesters can supply the average power needed for many applications, but cannot provide the high bursts of power needed, for example, to relay data across wireless networks. Mars will present at the IDTechEx Energy Harvesting and Storage USA conference in Denver, CO,
November 3 - 4, 2009.

WHO:
Pierre Mars, VP of applications engineering for CAP-XX, is a published authority on power management architectures using supercapacitors for space-constrained electronics devices. He jointly holds three patents on supercapacitor applications and has held executive and technical management positions at Racal Defence Electronics, Chubb Electronic Security, CAE Pty Ltd and Honeywell Industrial Control. He is also a member of the IEEE.

WHAT:
His presentation, "Using Supercapacitors to Manage Your Power" will outline power architectures using supercapacitors to store the energy from a low but steady energy-harvesting source, and then deliver the peak power needed to gather and transmit data via wireless sensors or over the cellular phone network. Mars will describe how to size and select a supercapacitor, tips when using them, and some design examples.

Raghu Das, CEO of IDTechEx, explained, "Supercapacitors, also known as ultracapacitors or electric
double-layer capacitors (EDLCs), have attracted recent attention over batteries as energy storage options
for engineers creating energy-efficient designs that demand long life or low-temperature operation."
Analyst firm IDTechEx specializes in printed electronics, energy harvesting and RFID technologies.

WHERE:
The IDTechEx Energy Harvesting & Storage USA, Grand Mesa Ballroom, Hyatt Regency Tech Centre,
7800 East Tufts Avenue, Denver, Colorado, 80237, USA.

WHEN:
Wednesday, November 4, 14:20 - 14:45, Track 1, "Batteries, Supercapacitors and Other Storage" session.

ABOUT CAP-XX:
Sydney, Australia-based CAP-XX develops thin, flat supercapacitors for space-constrained electronic devices. Supercapacitors resolve the performance limitations of batteries and other current-limited power supplies, and provide backup power if the primary power source fails.

CAP-XX supercapacitors, which are also licensed to manufacturing partner Murata, enable manufacturers to make smaller, thinner, longer-running and more feature-rich devices such as camera phones, solid state drives, handheld PCs and battery-free condition-monitoring systems using the company's BritePower™ architectures. The company is listed on the Alternative Investment Market (AIM) in London. For more information, visit http://www.cap-xx.com or email sales@cap-xx.com.
