Abstract
Li-O2 batteries are promising energy storage systems due to their ultra-high theoretical capacity. However, most Li-O2 batteries are based on the reduction/oxidation of Li2O2 and involve highly reactive superoxide and peroxide species that would cause serious degradation of cathodes, especially carbon-based materials. It is important to explore lithiumoxygen reactions and find new Li-O2 chemistry which can restrict or even avoid the negative influence of superoxide/peroxide species. Here, inspired by enzyme-catalyzed oxygen reduction/oxidation reactions, we introduce a copper(I) complex 3N-CuI (3 N=1,4,7-trimethyl-1,4,7-triazacyclononane) to Li-O2 batteries and successfully modulate the reaction pathway to a moderate one on reversible cleavage/formation of O-O bonds. This work demonstrates that the reaction pathways of Li-O2 batteries could be modulated by introducing an appropriate soluble catalyst, which is another powerful choice to construct better Li-O2 batteries.
