a Schematic illustration of the cross-sectional structure of ASSB with Li2OHCl0.9F0.1-LLTO and conventional tape-cast LIB electrodes. b Cross-sectional SEM images of LTO negative electrodes with Li2OHCl0.9F0.1-LLTO composite solid electrolyte prepared by thermal and pressure-assisted melt infiltrations. c SEM and ToF-SIMS mapping images of the NCA positive electrode cross-section after pressure-assisted melt infiltration. d STEM and STEM-EDX mapping image of an NCA positive electrode after pressure-assisted melt infiltration; Green, blue, and red represent Ni, Cl, and C, respectively. e Three-dimensional SEM cross-sectional image and the EDX mappings of Li2OHCl0.9F0.1-LLTO composite solid electrolyte prepared by pressure-assisted melt infiltration. The scale bars in b, c, d, and e are 2, 10, 2, and 10 μm, respectively.
