A platinum catalyst deposited on a zirconia support for the design of lithium-oxygen batteries with enhanced cycling ability.

A platinum catalyst supported on zirconia is proposed as a cathode in lithium-oxygen batteries. Experimental and theoretical studies show that zirconia suppresses the side-reactions of the intermediate (O2-) and the final product (Li2O2) by the stabilization of their reactivity. Thus, it is able to enhance the reversibility during charge/discharge in lithium-oxygen batteries.
