Scientists have built a tiny battery that provides power and cooling at the same time

When it comes to processors, heat is enemy number one. Packing ever more powerful processors into constantly shrinking mobile technology is a recipe for cramped cases and constantly troublesome heat buildup. Researchers from IBM and ETH Zurich think they may be on the verge of a truly novel solution, and it's based on a component that every mobile device already has: the battery. The scientists developed a pint-sized "flow battery" which uses electrolytes dissolved in two liquids to store a char...
