摘要（英）：

The invention provides a compound polymer electrolyte material, a preparation method thereof, an electrolyte membrane and an all-solid-state lithium secondary battery. The electrolyte material is prepared from a polymer matrix, alkali metal salt and sulfide inorganic electrolyte. The sulfide inorganic electrolyte is prepared from lithium-ion conductors with the general formulas in formula I(Li4-x1Ge1-x1Px1S4), the formula II (Li10+x2G1+x2P2-x2S12) and the formula III (Li3+5x3P1-x3S4) or Li2S-M type lithium-ion conductors. In the formula I, x1 is larger than 0 and smaller than 1; in the formula II, x2 is equal to 0 or 1, and G is selected from Si, Ge or Sn; in the formula III, x3 is larger than 3 and smaller than 0.27. M is selected from the compound of P2S5 and D. D is selected from one or more of LiI, Li3PO4, Li4SiO4, P2O5 and P2S3. The compound polymer electrolyte material has high lithium stability, an electromechanical window and high electric conductivity.
