Ex situ XPS measurements and analysis of NCM811 cathode retrieved from a, c Li||NCM811 cells and b, d Li||NCM811 cells with LiHMDS after 100 cycles at 60 °C, the charging/discharging current were 180 mA g−1/180 mA g−1. a, b Si 2p, c, d F 1s. e Ex situ TOF-SIMS analysis of NCM811 cathode retrieved from Li||NCM811 cells after 5 cycles at 60 °C, the charging/discharging current were 18 mA g−1/18 mA g−1. The cell was disassembled at fully discharged state. f Possible reaction mechanisms of LiHMDS. g Reaction energy diagram of LiHMDS.
