Facebook has just started testing lithium-ion batteries as the backup power source for its server racks and plans to roll them out widely next year. Lithium-ion has been too expensive until now, Corddry says, but its use in electric cars has changed the economics. It’s now more cost effective than the bulky, lead-acid batteries widely used in data centers today.

“The crossover moment for us was really electric cars, especially when Tesla and the [Nissan] Leaf and those guys took off,” Corddry said this week, as he showed a reporter around the hardware lab at Facebook’s Menlo Park, California, headquarters.

“The inflection point has just happened in the industry where lithium-ion is cheaper to deploy than lead-acid for a data center UPS.”
