Fig. 6: The Li|CSEs|NCM811 ssLMBs performance and influence of CGL on cathode structure evolution.
a Cycling performances and b galvanostatic discharge potential profiles of Li|CSEs|NCM811 batteries at different charging rates. c Capacity retention performance. d, e The Nyquist plots before and after cycling and f representative plots of imaginary impedance as a function of the log f (Debye plots) for Li|CSEs|NCM811 batteries at 1.0 C (200 mA/g). The vertical lines indicate the Debye peak positions. Where Rb, Ri, CPE1 and W0 is the battery resistance, interface resistance, constant phase element and warburg resistance, respectively. g, j In situ XRD patterns during the first charge-discharge cycle of Li|CSEs|NCM811 batteries. The charge-discharge curves were shown at the left and the enlarged views of the (003), (101) and (104) peaks were shown at the middle of each XRD pattern. h, k The (003) peaks position at the initial charge and full charge. i, l The (003) peak fitting result of the XRD pattern at the end of charge.
