New York State ultracapacitor manufacturer Ioxus is forging ahead in a market it says is growing by better than 50% a year, turning out product at a new headquarters facility in Oneonta and expanding its ultracap line.

The firm claims fundamental safety and performance advantages over batteries, especially for hybrid vehicle applications demanding quick pickup and release of power.

“Every OEM is in discussion with ultracapacitor companies, including Ioxus,” says company co-founder and international sales VP Chad Hall. Manufacturers with ultracapacitors either in service or coming soon include Mazda, Nissan, PSA Peugeot Citroën and Toyota, and bus manufacturers in China, he says.

Ultracap applications include start-stop systems and regenerative braking.

Ioxus commenced operations at its new 38,000-square-foot headquarters in July 2011. In January 2012, Ioxus gave word that its had acquired Japan’s Power Systems, Ltd., a Japanese manufacturer of flexible, slim-pack electric double layer capacitors. Ioxus secured a proprietary, high-power flat cell design and, it says, “technological building blocks for creating flexible ultracapacitor energy storage solutions for a variety of applications.”

‘Modules that Are Ready to Go’

The acquisition “gives us modules that are ready to go, fully designed with voltage indicators,” Hall says.

Ioxus launched the “iMOD” series of 16-volt, 58-farad ultracaps this past autumn and 3,000-farad iCAP cells in January, and with the latter laid claim to the lowest equivalent series resistance and highest power density on the market. The products beat the main competitors “electrically, mechanically and thermally,” Hall says. ESR means low internal temperature rise even in heavy service, significantly increasing both performance and durability.
