NOVELTY - A solid-state electrolyte manufacturing method involves mixing polyacrylonitrile resin and diatomite to obtain a mixture, stirring the mixture with diatomite NMP solvent to obtain a mud. The mud is shaped to bulk material. The bulk material is placed in high temperature furnace with nitrogen to obtain block-shaped diatomite, followed by placing the NMP solvent of block-shaped diatomite in high-temperature furnace with nitrogen under vacuum conditions to evaporate the solvent NMP, repeating the process for 6-8 times to obtain solid-state electrolyte.    USE - Method for manufacturing solid-state electrolyte for use in a lithium-sulfur battery.    ADVANTAGE - The method enables manufacturing electrolyte with high ion transmission ability, high conductivity and circulation property in a simple and cost effective manner.    DETAILED DESCRIPTION - A solid-state electrolyte manufacturing method involves mixing polyacrylonitrile resin and diatomite to mass ratio of 46-56:54-44 to obtain a mixture, stirring the mixture with 18-24 wt. % diatomite N-methylpyrrolidone (NMP) solvent to obtain a mud with uniform viscosity. The mud is shaped to bulk material according to the need of solid electrolyte. The bulk material is placed in high temperature furnace purged with nitrogen under vacuum evacuation to obtain block shape adhesive mud containing a carbon component of block-shaped diatomite. The lithium poly- sulfide, methyl amidogen butyric acid, lithium perchlorate, lithium phosphate to ratio of 58-66:33-18:6-8:3-8 dissolved in NMP solvent to form 18-33 wt. % poly-sulfide NMP solution, followed by immersing the block-shaped diatomite in poly-sulfide NMP solution for 13-18 minutes after heat treatment to remove the lithium-containing polysulfide, a-amino butyric acid, lithium perchlorate, lithium phosphate, diatomite, placing the NMP solvent of block-shaped diatomite in high-temperature furnace with nitrogen under vacuum conditions to evaporate the solvent NMP, repeating for 6-8 times to obtain the diatomite containing diatomite lithium polysulfide, a-amino butyric acid lithium perchlorate, lithium phosphate as 18-21 wt. % solid-state electrolyte.
