Ioxus ultracapacitors

Ioxus Inc. has rolled out a new family of large-cell prismatic electrochemical double-layer capacitors (EDLC) which is targeting transportation and utility applications, which are priced to be more cost-effective in terms of overall system designs.

The company claims the 1,000-, 3,000- and 5,000-Farad ultracapacitors are smaller in size compared to products of other industry players but offer increased energy and power density benefits.

The new ultracapacitors are targeting a wide range of high-power applications that require low-cost and long-operating-life energy storage systems for optimal performance. Key markets include transportation, electric utility, material handling, industrial bridge power and renewable energy generation.

Ioxus' high-performance, environmentally-safe products can quickly store and deliver energy in these demanding applications, providing a high-cycle life and a wide temperature operating range from -40C to +70C.

Ioxus EDLCs can be used as sole energy storage devices or can be combined with other types of energy storage devices, such as batteries or fuel cells, to meet the user power demand requirements. In this combination, ultracapacitors expand the system's charge and discharge capabilities into shorter response times, extend the life of other, lower-power elements and open up new options for energy storage applications.

Unlike competitors, Ioxus' ultracapacitors are particularly suited for applications where weight or system volume is important because of their high-power densities.

"The three major selling points of the new family are smaller size, low ESR and high power density," explained Chad Hall, chief operating officer for Ioxus. "The two markets we are really going for with these products are mass transit/transportation in general as well as utility stabilization. Advanced Power Components plc already has stock of the products at its facility in the UK".

Ioxus' new 1,000-, 3,000- and 5,000-F ultracapacitors are available and start at the following prices for low volumes:

1,000F, 2.7V ultracapacitors - $62

3,000F, 2.7V ultracapacitors - $90

5,000F, 2.7 V ultracapacitors - $175

Ioxus is also offering the following new designer kits starting at $149:

1 - 2000F prismatic ultracapacitor

1 - 600F cylindrical screw terminal ultracapacitor

1 - 400F cylindrical screw terminal ultracapacitor

2 - 220F cylindrical snap-in terminal pseudo-capacitors

2 - 100F cylindrical snap-in terminal ultracapacitors.
