Organic hydrogen peroxide-driven low charge potentials for high-performance lithium-oxygen batteries with carbon cathodes

Abstract

Reducing the charge potential is of importance to advance the performance of Li-O2 batteries. Here the authors show that hydrogen peroxide solution allows decomposition of lithium hydroxide at ∼3.5 V and the organic urea hydrogen peroxide additive enables a charge potential of only about 3.26 V and stable cycling for non-aqueous Li-O2batteries.
