A team at #MIT has come up with a lithium-based battery system that soaks up carbon dioxide directly from inside power plants, converting the waste steam into a (#CO2-loaded) electrolyte – one of the three main parts of a battery.

#Lithium-carbon-dioxide batteries typically require metal catalysts to function, because carbon dioxide is not very reactive. The problem is, the catalysts can be expensive to source, and the chemical reactions involved can be difficult to control.

To get around this, a team led by mechanical engineer Betar Gallant achieved electrochemical carbon dioxide conversion without the metallic catalyst, using only a carbon electrode.

The answer was to use CO2 in a liquid state, incorporating it into an amine solution.
