Ultracapacitor Maker Ioxus Raised $15M in Series-C Funding, Seeks $20M

Ioxus, Inc. received $15 million in Series-C Funding and is seeking to raise $20 million in total.  The round was led by the The Westly Group with participation from Northwater Capital Management, Braemar Energy Ventures, Energy Technology Ventures, and Aster Capital. The company makes ultracapacitors that rapidly absorb and release high-voltage power.  The devices can store power generated by solar and wind farms or be paired with batteries in electric vehicles to capture energy from braking. A spin-off from 40-year-old Custom Electronics, Inc. in Oneonta, Ioxus emerged as a standalone company in 2007.
