Award recognises supercapacitor breakthrough
Cap-XX has received an award from Frost and Sullivan for the research that led to a breakthrough nanotechnology process for producing thin and flat supercapacitors for portable devices
Cap-XX has received Frost and Sullivan's 2005 Technology Innovation of the Year Award in nanotech-enabled energy devices (supercapacitors) for the company's research that led to a breakthrough nanotechnology process for producing thin and flat, or prismatic, Supercapacitors to meet the pulse-power requirements of portable devices.

EDN has selected the supercapacitor-based BriteFlash LED flash power architecture from Cap-XX as a finalist for this year's EDN Innovation Awards
The award is presented to a company whose research is expected to bring significant contributions to the industry in terms of adoption, change, and competitive posture.
The award also recognises the quality and depth of a company's research and development program, as well as its vision and risk-taking.
Supercapacitor technology can help bridge the gap between capacitors and batteries, delivering higher power bursts than batteries and storing more energy than capacitors.
Supercapacitors provide the high power bursts required, without draining the battery, when taking a digital photo or sending wireless cellphone transmissions, for example.
Frost and Sullivan recognises Cap-XX's research in developing supercapacitors compact enough for increasingly smaller consumer electronics.

'Cap-XX has applied nanotechnology solutions and processes in its designs to produce carbon electrodes smaller than a postage stamp, but with a surface area of hundreds of square meters', notes Frost and Sullivan Research Analyst Viswanathan Krishnan.
'The result is high energy and power densities in the smallest packages'.
The company leveraged expertise in carbon chemistry from its strategic partner CSIRO, Australia's largest research organisation, to help achieve this result.
Cylindrical-type supercapacitors have been around a while, but have traditionally been used for low power backup applications.
This type supercapacitor is larger and has very high equivalent series resistance (ESR), so is not suitable for small handheld applications.
The breakthrough Cap-XX has achieved is very high capacitance with very low ESR, providing the industry's highest energy and power densities in a thin, flat, prismatic package.
Cap-XX prismatic supercapacitors feature a small footprint of either 28 x 17 or 39 x 17mm, and a thin profile of 1 to 3mm.
They allow designers to produce thinner, longer-running devices with functions that were previously impossible, such as LED flash camera phones that produce clear pictures even in low light.
'Cap-XX's technology targets high growth applications such as smart phones, camera phones, GPRS/Edge/3G devices, PCMCIA and CompactFlash cards, ruggedised PDAs, digital still cameras, automated meter reading, MP3 players, wireless sensor networks, location tracking and medical devices', continued Krishnan.
'It can also play a role in meeting the peak power demands in renewable energy sources such as fuel cells and solar power devices'.
