New battery gobbles up carbon dioxide
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. Rather than attempting to convert carbon dioxide to specialized
chemicals using metal catalysts, which is currently highly challenging, this
battery could continuously convert carbon dioxide into a solid mineral
carbonate as it discharges.
While still based on early-stage
research and far from commercial deployment, the new battery formulation could
open up new avenues for tailoring electrochemical carbon dioxide conversion
reactions, which may ultimately help reduce the emission of the greenhouse gas
to the atmosphere.
The battery is made from lithium
metal, carbon, and an electrolyte that the researchers designed.
