Northwestern University researchers are reporting that doping tin selenide with sodium boosts its performance as a thermoelectric material. The newly devised material produces a significantly greater amount of electricity than the undoped material, given the same amount of heat input. The researchers can confidently suggest the material pushes thermo electric technology closer to commercial usefulness. […]

Sumitomo Electric Industries of Japan has developed a rechargeable molten-salt battery that promises to cost about 10% as much as lithium ion batteries.  Sumitomo Electric working with researchers at Kyoto University has developed a sodium material that melts at only 57º C, just 134º F.  This is news. With about double the energy density of […]
