Toyota Motor Corp., the world’s largest seller of hybrid autos, said it’s developing a magnesium battery that holds twice the energy of lithium-ion cells as automakers seeks better ways to power electric cars.

The company’s technical center in Ann Arbor, Michigan, is working on the magnesium-sulfur battery, complementing development of other future electric-power chemistries at Toyota labs in Japan, Jeffrey Makarewicz, the engineer managing the U.S. project, said in an interview at the North American International Auto Show in Detroit.
