Oxygen reactions in a non-aqueous Li+ electrolyte Peng, Zhangquan Freunberger, Stefan Alexander ; https://orcid.org/0000-0003-2902-5319 Hardwick, Laurence J. Chen, Yuhui Giordani, Vincent Bardé, Fanny Novák, Petr Graham, Duncan Tarascon, Jean-Marie Bruce, Peter G. 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.
