GM and Envia System claim 400 Wh/kg batteries wil be commercial in 2014 to 2016

From NextBigFuture.com

Envia is a high energy density leader in the lithium-ion battery space, having developed intellectual property and cell prototypes using Envia cathode, anode and electrolyte. Envia is engaged with automotive OEMs around the world – developing custom cathode material, electrolyte and cell designs for these OEMs automotive applications. As a proof of technical leadership, Envia has also demonstrated the world’s first 400Wh/kg in large format pouch cells.

Business Week – Envia is backed by General Motors. They are working on batteries that could power an electric car 100 or even 200 miles on a single charge in the next two-to-four years, GM’s CEO said Thursday.

GM is sure that the battery will be able to take a car 100 miles within a couple of years, he said. It could be double that with some luck, he said.

“I think we’ve got better than a 50-50 chance,” Akerson said, “to develop a car that will go to 200 miles on a charge,” he said. “That would be a game changer.”
