Summary: | The invention belongs to the technical field of solid-state lithium-sulfur batteries, and particularly relates to a preparation method of a composite solid-state electrolyte membrane with a transition layer for a lithium-sulfur battery. Comprising the following steps: (1) dispersing LGPS into a solvent, adding polyethylene glycol, dissolving, then adding a silane coupling agent, carrying out heat preservation stirring, adding polyethylene oxide, dissolving, then adding imidodisulfuryl fluoride lithium salt to obtain a mixed solution, casting the mixed solution into a mold, and drying to obtain an electrolyte base membrane; and (2) dispersing LGPS and SuperP-Li into a solvent, adding polyethylene glycol, dissolving, then adding a silane coupling agent, carrying out heat preservation and stirring, adding polyethylene oxide, dissolving, then adding bis (fluorosulfonyl) imide lithium salt to obtain black slurry, pouring the black slurry into the mold in the step (1), and drying to obtain the composite solid elect |
