Abstract

Abstract : There are various reaction mechanisms in the discharge process of a non-aqueous lithium air battery (LAB). Recently, it has been identified that low current rate and high donor number solvents can lead to solution phase reaction, but high current rate and low donor number solvents will cause thin film growth covering the active cathode surface. In this paper we extend our previous LAB multiscale model, which considers the thin film growth mode, to the general case where both surface thin film growth and solution phase reaction coexist. A detailed mechanism is proposed and simulation results are compared with experimental data.
