New metal mix could lead to cheap, plentiful sodium-ion batteries in gadgets

Lithium batteries very frequently power our gadgets, but the material itself isn't common and, by extension, isn't cheap. Researchers at the Tokyo University of Science aim to solve that through sodium-ion batteries using a new electrode material. By mixing together oxides of iron, manganese and sodium, Shinichi Komaba and team have managed to get a sodium battery's electrode holding a charge closer to that of a lithium-ion battery while using a much more abundant material.
