Silver-zinc battery developer Zinc Matrix Power Inc. received a $7 million investment to create and staff a pilot production facility in Camarillo. The money is coming from existing investors, which include Intel Capital, a large private equity group, and OnPoint Technologies. The company is planning eventually to move into full-scale production of its batteries, which are designed to be used in military and consumer electronics. CEO Dr. Ross Dueber said the batteries could provide double the energy provided by current lithium-ion batteries.
