Kleiner’s secretive battery-ultracapacitor company, EEStor

If you’re not reaching, engaging, and monetizing customers on mobile, you’re likely losing them to someone else. Register now for the 8th annual MobileBeat, July 13-14, where the best and brightest will be exploring the latest strategies and tactics in the mobile space.

Kleiner Perkins, the well-known Silicon Valley venture capital firm, is backing an obsessively secret company called EEStor, which says it has developed a battery-ultracapacitor technology that “blows away” current lithium-ion technology in all aspects of performance.

See the story here by Toronto Star’s Tyler Hamilton.

The company doesn’t even want its response published, but Toronto Star publishes it anyway:

“EEStor is not making public statements at present time,” company co-founder and chief executive Richard Weir replied when the Toronto Star requested an interview via email. “EEStor would also like to have you and your paper not publish any articles about our company and the Toronto Star is certainly not authorized to publish this response.”

This isn’t entirely new. We mentioned EEStor before, pointing to a piece that said Kleiner had led a $3M investment into the company. But Toronto Star has more details.
