Making batteries go further

Current research efforts to increase range include improved battery technologies such as IBM’s lithium-air battery  that could lead to an EV with a 500-mile range and Phinergy’s aluminum-air energy storage device  that could increase an EV’s range to 1,000 miles. Another way to increase range is to lighten the vehicle.

From Mitsubishi’s motor-inverter combo pack, which is half the size and significantly lighter than the company’s existing motor and external
inverter, to RMI’s work on carbon fiber composites, there are many ways people are working to lighten the weight of vehicles.

An IBM-spearheaded effort in Europe is likewise working to enable access to the continent’s network of charging systems, regardless of the EV owner’s home service or network, as the European Union in parallel approved a common charging standard  and plug, which should enable greater access to charging networks.
