Work is continuing on IBM's wish-we-had-it-now lithium-air battery technology. Today, IBM is announcing that two new partners – Asahi Kasei and Central Glass – are joining the Battery 500 Project team. The idea, as the number suggests, is to develop a battery for passenger cars that can provide enough energy to go 500 miles. The secret? Energy pulled from thin air.

Last week, a consortium of some of the nation's leading scientists and engineers reportedly met in California to develop a new battery pack for electric cars. Sponsored by IBM and its Big Green Innovations program, the so-called Battery 500 team hopes to create a power pack capable of propelling a vehicle for up to 500 miles.
