Better Lead Acid Batteries Built with Hard Drive Tech

Leigh Hutchens — Sat, 09 Mar 2013 10:27:30 +0000

Over the past three years, Gridtential has been slowly developing a better lead acid battery by using chip and hard-disk drive manufacturing processes. Gridtential used a grant from the California Energy Commission to demonstrate that its lead acid battery is far better than standard lead acid batteries. The company’s batteries have two times the energy density […]
