Fig. 6: Electrochemical performance of the Li-In | LPSCl-LZCO | scNMC811 cell.

a Initial charge and discharge voltage profiles at 20 mA g–1, with the Coulombic efficiency ηCoulomb denoted. b, c Rate capability at 20, 40, 66, 100, and 200 mA g–1. d Long-term cycling performance at 1000 mA g–1. All the cycling tests were conducted between 2.18 and 3.68 V vs. Li-In/Li+ at 25 °C and 1.5 tons of applied external pressure.
