a The cross-sectional SEM image and corresponding elements distribution of the CFLLO composite positive electrode filled with LDFB + LPF GPE. b The first charge/discharge curves of the Li|GPE | CFLLO cells in 2.0–4.8 V at 25 mA g−1 and 30 °C. The marked capacities with triangles represent the lattice oxygen plateau. c, d The charging voltage profiles in 2.0–4.8 V and corresponding in situ DEMS results of mass signals of m/z 44 (CO2, CH3CHO) for the Li|Base GPE | CFLLO (c) and Li|LDFB + LPF GPE | CFLLO (d) batteries. e, f SEM images of composite positive electrode with Base GPE (e) and LDFB + LPF GPE (f) after cycling. g The impedance parameters of bulk (Rb), CEI (RCEI), and interface (Ri) of the corresponding batteries from fitting results.
