A research team and the Georgia Institute of Technology has invented a lithium ion battery that charges itself by using the environment vibrations. Unlike other similar devices, this one is highly efficient, because it converts mechanical energy to chemical energy directly, without using electricity as a middleman. A piezoelectric membrane is at the Lithium Cobalt […]
