New lithium technology dramatically increases battery life

Researchers at the University of Waterloo have been able to increase Lithium battery power by more than three times through the use of a new composite material. This material contains sulphur which has been attempted a number of times before by other scientists without success.

"The challenge had been to find a way to keep the electrically active sulphur in intimate contact with a conductor such as carbon. The researchers took mesoporous carbon, a material riddled with extremely fine channels that are about 1/20,000th of the width of a human hair. When it was put in contact with melted sulphur, the hot liquid was drawn by capillary forces into the channels, where it solidified into nanofibres."
