Electrofuel Inc. (Toronto) announced that its new Lithium-Ion SuperPolymer battery has almost doubled the previous endurance record of rechargeable batteries. The new SuperPolymer battery has an energy density of 470Wh/litre and 183Wh/kg, and is claimed to be able to power laptop computers for 15 hours or more when fully charged. The first product based on this technology is Electrofuel's Powerpad line of computer batteries. Electrofuel is targeting its battery for application in computers, cellular phones, telecommunications, portable GPS, defense and portable medical devices, as well as future application in electric cars, electric bicycles, load leveling for electric utilities, and alternative energy businesses such as solar and wind energy storage. The battery's superpolymer design enables it to be molded into virtually any form to fit the shape of any device, according to Electrofuel. The battery pack can be as thin as a credit card or the size of a briefcase to power electric vehicles. The 160Wh Powerpad 160, available now, offers a run time of about 15 hours. Powerpad 50, 100 and 200 models will be available soon. Pricing for the Powerpad family is $199 to $799.
