Taking the shortcut: Spectroscopic data (see picture) provide direct evidence that in non-aqueous Li+ electrolyte, O2 is reduced to O2−, which then forms LiO2 on the electrode surface which disproportionates to Li2O2. On charging, Li2O2 decomposes directly, in a one-step reaction to evolve O2 and does not pass through LiO2 as an intermediate.
