Waste battery heat converted to electricity

New technology allows researchers to capture low temperature (below 100C) waste energy from batteries.

Researchers at Stanford University and the Massachusetts Institute of Technology have developed a method of recovering waste heat through a principle known as the thermogalvanic effect.

This principle – that the voltage of a rechargeable battery is determined by temperature – allowed researchers to use waste heat to recharge batteries, generating more electricity than was required to charge them.
