a Cross-sectional STEM image. b–d The HR-STEM images for the layered NMC structure and the rock-salt phase at the primary particle surface after 100 cycles at a fully discharged state of the In|LGPS | PS-LPO-NMC811 cell. e The HADDF-STEM image and the corresponding elemental mapping from the PS-LPO-NMC particles after 100 cycles at a fully discharged state of the In|LGPS | PS-LPO-NMC811 cell. The cells were cycled at 0.178 mA cm-2 at 25 °C.
