Battery Advance Could Lead To a Cleaner Way To Store Energy 147
sciencehabit writes: With the continuing rise of solar and wind power, the hunt is on for cheap batteries that are able to store large amounts of energy and deliver it when it's dark and the wind is still. Last year researchers reported an advance on one potentially cheap, energy-packing battery. But it required toxic and caustic materials. Now, the same team has revised its chemistry, doing away with the noxious constituents—an advance that could make future such batteries far cheaper and simpler to build.
