With a high energy density, Li-O2 batteries have become a state-of-the-art battery technology. Inside the Li-O2 battery, the generation and disintegration of the discharged product solid lithium peroxide (Li2O2) have a significant effect on the battery’s performance. Previous research has shed little light on Li2O2 ‘s form and distribution inside, leaving questions regarding the trend and contributing factor of internal Li2O2 ‘s change in form and size unanswered.
