Research on CCS technology has generated a good understanding of the carbon-capture process that takes place inside a CCS system. When CO₂ is added to an amine solution, molecules of the two species spontaneously combine to form an “adduct,” a new chemical species in which the original molecules remain largely intact. In this case, the adduct forms when a carbon atom in a CO₂ molecule chemically bonds with a nitrogen atom in an amine molecule. As they combine, the CO₂ molecule is reconfigured: It changes from its original, highly stable, linear form to a “bent” shape with a negative charge — a highly reactive form that’s ready for further reaction.

In her scheme, Gallant proposed using electrochemistry to break apart the CO₂-amine adduct — right at the carbon-nitrogen bond. Cleaving the adduct at that bond would separate the two pieces: the amine in its original, unreacted state, ready to capture more CO₂, and the bent, chemically reactive form of CO₂, which might then react with the electrons and positively charged lithium ions that flow during battery discharge. The outcome of that reaction could be the formation of lithium carbonate (Li₂CO₃), which would deposit on the carbon electrode.
