Working Prototype of Magnesium Batteries for Cell Phone and Cars and Magnesium Recycling by Lasers for Renewable Energy Cycle

Abstract

We report the present status of development of magnesium batteries. Working prototype for cell phone and cars are already prepared and tested. These batteries use film-type magnesium and the efficiency is very high leading to high current and battery becomes very compact. For larger output, it is already demonstrated that the one cell can achieve several tens A(ampere), which is applicable to automobiles, and will reach 100A within a year. For smaller output, it can be compact and can drive a cell phone for one month without charging.
