Abstract:
Lithium-oxygen batteries (LOBs) can suffer from large charge overpotentials during the sluggish oxygen evolution reaction (OER). Here, a strategy used in the photo-electrochemical (PEC) water oxidation area is integrated into hybrid LOBs. Coating α-Fe2O3 with NiOOH results in enhanced electrochemical properties, and the as-assembled hybrid LOBs deliver a low charge voltage of 3.03 V, high energy efficiency of 88%, and long-term stability for over 350 hours.

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,...
