a Schematic illustration showing the architecture of H-SSE. b C 1s, F 1s, N 1s, and Ti 2p XPS profiles of the H-SSE derived SEI after Ar sputtering for 5 min. c Electron conductivities at 22 °C of LATP, PCE, and H-SSE measured under an SS-SS cell configuration, 150 mV polarization, and r.t. conditions. d Voltage-capacity curves of Li0|H-SSE|LFP full cell at 50 °C showing the rate capability. The loading of LFP is 1.95 mg/cm2. e Performance of H-SSE-based full cells when employing LFP at 22 °C (4.48 mg/cm2) and 50 °C (1.95 mg/cm2). f Performance of H-SSE-based full cells at 22 °C when employing high-loading NMC811 (7.4 mg/cm2). g Performances of H-SSE-based and PA-SPE-based full cells at 50 °C when employing a high-Ni, zero-Co, zero-strain cathode (2.89 mg/cm2). The right y-axis displays the Coulombic efficiency of the H-SSE-based full cell, while the Coulombic efficiency of the PA-SPE-based full cell is shown in Supplementary Fig. S32.
