Li7P2S8I (LPSI) electrolytes were directly produced on a cathode active material LiNi1/3Mn1/3Co1/3O2 (NMC) using the new liquid process which is named 'SEED method'. The formation of electrolytes on NMC was confirmed using scanning electron microscopy and energy dispersive X-ray mapping. The ionic conductivities of the LPSI electrolyte prepared by the SEED method were evaluated and the LPSI electrolyte showed 2.5x10(-4)Scm(-1) at room temperature which is almost equal to that of the LPSI electrolyte prepared by the previous liquid-phase shaking process. All-solid-state cells composed of [90MNC center dot 10LPSI composite vertical bar Li3PS4 vertical bar In-Li] were fabricated and the electrochemical properties of the cells were evaluated. The cell fabricated using this composite as cathode material exhibited enhanced performance in comparison with the cell using the cathode material prepared by hand mixing LPSI with NMC.
