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

Abstract

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.
