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.

Spontaneous redox reactions occur abundantly in nature. The chemical reaction occurring in a disposable AA battery powering our remote controls is one such example of a spontaneous redox reaction. Another example is the immersion of coiled copper wire into an aqueous silver nitrate solution. The reaction shows a gradual, visually impressive color change from colorless to bright blue and the formation of a grey precipitate on the copper wire. In this experiment,...
