Tech - Extended battery life of laptops, mobiles soon

Imagine talking on your cell phone or working on your laptop without having to recharge its battery for hours.

Your imagination may soon turn into realityƂ—thanks to researchers in Korea who have developed a new material for graphite anodes, which they claim could give the rechargeable Lithium ion batteries a power boost. A team at Hanyang University in Korea has developed the material which involves three-dimensional, highly porous silicon structures, the latest edition of Angewandte Chemie journal reported. According to the researchers, a Lithium ion battery contains a cathode (positive electrode) made of a mixed metal oxide, such as lithium cobalt oxide, and an anode made of graphite.
