(MoneyWatch) General Motors (GM) believes a company it backs may develop an electric car battery that can go up to 200 miles on a single charge, GM CEO Dan Akerson said this week.
Speaking at an employee meeting, Akerson said a small battery company backed by GM is working on a lithium-ion battery that can store more energy than the current generation. That should lead to a range of at least 100 miles per charge, and possibly as much as 200. "I think we've got a better than 50-50 chance to develop a car that will go to 200 miles on a charge," said Akerson. "That would be a game changer."
GM's current electric car, the Chevrolet Volt, can go only about 35 miles on one charge before its backup gasoline engine kicks in. The Tesla S claims 300 miles on a charge but it has a much larger battery and is a much more expensive car.
However, the Volt's possibility of backup powervs. all-electric cars such as the Nissan Leaf.
The company developing the new battery is Envia Systems, based in Newark, Calif. GM invested $7 million in Envia in 2011. "These little companies come out of nowhere and they surprise you," Akerson told employees.
Envia seems to be faring better than A123 systems, which this week wasAnalysts say that electric car battery firms that survive likely will have an alliance with major companies, as Envia does.
