One of the main consideration when building an electric vehicle is how to deal with excess heat build up in battery packs. To ensure the safe operation of lithium ion batteries must be cooled to an optimal temperature. But what if that heat could be turned back into electricity? It might sound farfetched, but a group of scientists has developed a “gel” — a thermogalvanic gel to be precise — that can simultaneously cool batteries and turn heat into electricity.
