Solicore, a US-based maker of batteries, has raised $9m of its planned $15m series E round from 10 investors.
In a regulatory filing first seen by CityBizList, Solicore, which makes small batteries to power credit cards (pictured), has Andrew Teichman, executive director of investments at OPG Ventures, the corporate venturing unit of Canada-based Ontario Power Generation, and Robert Daigle, chief technology officer of local industrial group Rogers, as its directors.
Rogers and OPG had previously backed Solicore’s $13.3m D round in December 2009, as well as venture capital firms Draper Fisher Jurvetson, Rho Ventures, Braemar Energy Ventures and Firelake Capital.
