Next generation ultracapacitor technology promises high performance energy storage benefits

January 23, 2012 // By Paul Buckley
In this news analysis article EE Times Europe Power Management's editor, Paul Buckley finds out more about the Ioxus Inc's new iCAP 3,000 Farad ultracapacitor by talking to Chad Hall who is Vice President of Sales for Ioxus Inc and one of the founders of the company.  The new device claims to represent the lowest weight, lowest equivalent series resistance (ESR) and highest power density ultracapacitor available in the market for energy storage cells.

eeNews Europe: What has been focusing on in the past twelve months?

Hall: In April 2011 Ioxus received $21 million of investment from a number of companies including Energy Technology Ventures (a GE-NRG Energy-ConocoPhillips joint venture), Northwater Capital through its Northwater Intellectual Property Fund, Aster Capital (representing Alstom, Schneider Electric and Rhodia) and return investor Braemar Energy Ventures.   

The funding enabled us to move into a new manufacturing facility so we took over the National Soccer Hall of Fame Facility in the USA which is a beautiful showcase facility.  We retro-fitted the building in June 2011 and it has given us about five times more space than we had previously.  We have also opened an office in China.  We have several field applications engineers there now as well as quite a large distribution network.

Last year our product bookings increased seven times compared with 2010 and we have increased our staff by three times during the 2010 to 2011 period.  We are now planning to launch our next generation iCAP 3,000 Farad ultracapacitor.

eeNews Europe: What do you see as the key application areas you are aiming to address with the new iCAP 3,000 Farad ultracapacitor?


Hall: The iCap is a next generation ultracapacitor technology that is based on better performance electrically, mechanically and thermally.  

The big applications for the larger devices really fall in three major categories.  The first one is transportation drives and systems.  This would include hybrid buses.  They actually use the ultracapacitors on board to accelerate the vehicle and then they recapture energy during braking.

The second application is light rail has several applications from on-board storage for when they ride through gaps in power stations. The ultracapacitors also do some on-board storage to accelerate the vehicle.  Mainly in Europe they are looking at ways to put train stations in city centers without having to have the ugly overhead power lines.  So ultracapacitors
