Research team reports major breakthrough in lithium battery technology
An NSERC-funded lab at the University Of Waterloo has laid the groundwork for a lithium battery that can store and deliver more than three times the power of conventional lithium ion batteries. The research team of professor Linda Nazar, graduate student David Xiulei Ji and postdoctoral fellow Kyu Tae Lee are one of the first to demonstrate robust electrochemical performance for a lithium-sulphur battery. The finding is reported in the on-line issue of Nature Materials. more

Air-fuelled Battery Offers 10-Fold Increase in Capacity
A new type of low cost, air-fuelled battery is claimed to be able to offer up to ten times the energy storage of designs currently available. Improved capacity is thanks to the addition of a component that uses oxygen drawn from the air during discharge, replacing one chemical constituent used in rechargeable batteries today. Not having to carry the chemicals around in the battery offers more energy for the same size battery. more
