In situ visualization of synergistic effects between electrolyte additives and catalytic electrodes in Li–O2 batteries

Abstract

By using in situ atomic force microscopy, Li–O2 interfacial reactions promoted synergistically by the electrolyte additive K+ and Pt nanoparticles electrode are visualized. The Pt nanoparticles electrode promotes the formation of the intermediate lithium superoxide (LiO2) and K+ assists its diffusion into the electrolyte, thereby promoting the formation of large-sized discharge products during discharging and increasing the discharge capacity of the Li–O2 battery. These results provide direct evidence for clarifying the interfacial synergy mechanism of electrolyte additives and solid catalysts.
