An MIT team is working on developing lighter batteries which could be used in electric cars, cell phones and computers.

Researchers at the MIT are working on a technology which could make batteries lighter while delivering a lot more energy. Lithium-oxygen batteries are similar to the conventional lithium-ion batteries used in portable electronic devices, but promise to be lighter as they would use lightweight carbon electrodes.

The research team is working to develop electrodes with an even higher efficiency than carbon electrodes and have experimented with gold and platinum with positive results. The researchers say that while it is too early to predict when lithium-oxygen batteries will be available for commercial uses, they could be used in electric cars, computers and cell phones in the future.
