a Charge/discharge curves of the first cycle at 0.089 mA cm−2, b GITT curves during the discharge process, and c corresponding Li+ diffusion coefficients of the three kinds of NMC811 cathodes during different discharge states. The error bar of GITT data is around 2%, which is original from the mechanism error bar in this testing (±0.5 μA) and the data analysis (±0.1 mV). d–f The dQ/dV curves of the three kinds of NMC811 cathodes during the initial 100 cycles at 0.178 mA cm-2. g Rate capabilities and h cycling performance of the three kinds of NMC811 cathodes. Red for the PS-LPO-NMC811 cathode, green for the LPO-NMC811 cathode, and orange for the NMC811 cathode.
