New Battery Gobbles up Carbon Dioxide

This scanning electron microscope image shows the carbon cathode of a carbon-dioxide-based battery made by MIT researchers, after the battery was discharged. It shows the buildup of carbon compounds on the surface, composed of carbonate material that could be derived from power plant emissions, compared to the original pristine surface (inset).

Lithium-based battery could make use of greenhouse gas before it ever gets into the atmosphere. A new type of battery developed by researchers at MIT could be made partly from carbon dioxide captured from power plants...
