Fig. 2: Cross-sectional SEM images of Li-In|LPSCl|LNO@NCM622 cells with different cycling numbers.

a The cell after resting for 60 days without cycling. b The cell after 100 cycles. c The cell after 897 cycles. The cells in (b) and (c) were cycled at 3.8 mA cm−2 under a pressure of 150 MPa within the potential range of 2.1–3.68 V.
