Comparison of the lithium-ion bulk and interface conductivities. Lithium-ion conductivity for bulk Li6PS5Br determined by 7Li solid-state NMR spin-lattice relaxation (SLR) experiments and the conductivity over the Li6PS5Br–Li2S interface from 2D/1D NMR exchange experiments for different cathode mixtures, I: micro Li2S–Li6PS5Br, II: nano-Li2S–Li6PS5Br, III: mixed nano-Li2S–Li6PS5Br, IV: annealed mixed nano-Li2S–Li6PS5Br and V: mixture III cycled (see Fig. 1a)
