To examine the discharge behavior of their system, the researchers set up an electrochemical cell consisting of a lithium anode, a carbon cathode, and their special electrolyte — for simplicity, already loaded with CO2. They then tracked discharge behavior at the carbon cathode.
As they had hoped, their special electrolyte actually promoted discharge reaction in the test cell. “With the amine incorporated into the DMSO-based electrolyte along with the lithium salt and the CO2, we see very high capacities and significant discharge voltages — almost three volts,” says Gallant. Based on those results, they concluded that their system functions as a lithium-CO2 battery with capacities and discharge voltages competitive with those of state-of-the-art lithium-gas batteries.
The next step was to confirm that the reactions were indeed separating the amine from the CO2 and further continuing the reaction to make CO2-derived products. To find out, the researchers used a variety of tools to examine the products that formed on the carbon cathode.
