Fast Li₂O₂ Electrochemistry Enabled by Co-N_x/Co (111) with Optimized Intermediate Adsorption.

ABSTRACT: The practical development of Li-O₂ batteries (LOBs) urgently needs to explore robust cathode catalysts to boost the sluggish Li₂O₂ reaction kinetics and parasitic reactions despite their theoretically high specific energy. Profound understanding of the cathode properties and the battery performance is rather critical in developing rational-designed electrocatalysts. In this study, a Co-N_x/Co (111) decorated N-doped hierarchical carbon framework (Co-N_x/Co@NHCF) is proposed as an efficient cathode in LOBs. Spectroscopic analysis coupled with experimental results suggests that the Co-N_x/Co (111) catalytic center can significantly reduce the battery overpotential, and meanwhile, the hierarchical carbon framework ensures rapid ma
