A research team at the Fraunhofer Research Institution for Electronic Nano Systems (ENAS) in Chemnitz, Germany, led by Prof. Dr. Reinhard Baumann, have developed a 1.5V battery that weighs less than a gram, is less than 1mm thick, and can be printed using a process similar to that used in silk screening. The new type […]
Here’s a nice demonstration of an aluminum-air battery which produces 1.0 V and 100 mA from the oxidation of aluminum foil. Metal-air cells such as this find common application in hearing aid batteries, for instance, which are driven by the oxidation of zinc. More: How-To: Backyard battery The Supercap battery
