A new kind of portable electrochemical battery that can produce thousands of hours of power – and soon replace the expensive regular or rechargeable batteries in hearing aids and sensors and eventually in cellphones, laptop computers and even electric cars – has been developed at Haifa’s Technion-Israel Institute of Technology.

The unique battery is based on silicon as a fuel that reverts to its original sand. The battery can also be left on the shelf for years and inserted into a device to provide immediate power.
