The invention discloses an assembly method of a conductive colloid electrolyte lithium-air battery. Conductive colloid is dispersed in a conventional electrolyte containing a support electrolyte and an organic solvent to form a conductive colloid electrolyte, the assembly of the conductive colloid electrolyte lithium-air battery starts from a negative electrode and is performed in a glove box, thesequence from bottom to top is a negative electrode cover, a gasket, an elastic sheet, a Li sheet, a separator, a positive electrode and a positive electrode porous cover, the Li sheet is taken out of impregnated PC, the residual PC is washed by the electrode and is placed on the gasket, in the positive electrode, commercial carbon black and a multi-walled carbon nanotube or graphene are preparedto form a dispersing liquid, the dispersing liquid is spayed on carbon paper, fabrication is done after cutting and dying, package is performed after assembly is completed, the product is placed in the glove box for standing after package, and the conductive colloid electrolyte lithium-air battery is obtained. The assembled conductive colloid electrolyte lithium-air battery has the advantages ofgood cycle property, simple preparation process, low production cost and the like, and convenience and application are convenient.
