Magnesium may provide key to smaller, denser batteries

Researchers at the Toyota Research Institute of North America (TRINA) in Michigan have made a discovery that could lead to batteries that are smaller and cheaper to produce than lithium-ion units found in most electric cars sold today but with superior range. The key is magnesium, which is already quite common in car frames and wheels. Magnesium... Magnesium may provide key to smaller, denser batteries
