This study demonstrates that surface modification of a carbon-paper cathode by oxygen functional groups expands the potential region for the sustained discharge of non-aqueous Li-O-2 batteries. Expansion of the potential region is considered to be due to a decrease in the over-potential for the oxygen reduction reaction and modification of the electrochemical adsorption isotherm of LiO2, which is an important adsorbed intermediate that determines the discharge capacity.
