a Photograph of an ASSB coin cell. b Detailed schematic of the internal structure of the ASSB coin cell. c Processed image of the ASSB junction obtained through SEM-EDX imaging. d, e Nyquist plots of impedance and initial charge-discharge characteristics at 298 K for ASSBs with different oxide solid electrolyte fillers. f Cycle performance of the ASSB using Li2OHCl0.9F0.1-LLTO composite solid electrolyte at 333 K under a charging/discharging current of 50 mA g-1 (corresponding to 0.3 C). The last data point after 100 cycles was obtained using a charging/discharging current of 10 mA g-1 (corresponding to 0.1 C) to minimize the effect of cell resistance. g, h Rate performance at 298 K for ASSBs utilizing small NCA particles (D50: 5 µm) and a thin solid electrolyte layer (thickness: 50 µm), selected to reduce ionic resistance and enhance rate performance. Source data are provided as a Source Data file.
