NOVELTY - A multi-layer electrolyte lithium-air battery production method involves preparing an air electrode by taking insulating porous film material as an air transmitting layer and mixing synthetic graphite, PTFE emulsion and manganese dioxide catalyst to obtain a mixture. The mixture is coated on a side of the air transmitting layer and pressed by using a roller to obtain a product. The product is heated until a uniform sheet layer is obtained to prepare an air reaction layer, followed by taking aluminum mesh, titanium meshes or steel mesh as current collector.    USE - Method for preparing multi-layer electrolyte lithium-air battery.    ADVANTAGE - The method enables preparing multi-layer electrolyte lithium-air battery with better safety and reliability.    DETAILED DESCRIPTION - A multi-layer electrolyte lithium-air battery production method involves preparing an air electrode by taking insulating porous film material as an air transmitting layer and mixing (in mass%) synthetic graphite (30-90), PTFE emulsion (5-50) and manganese dioxide catalyst (0-50) to obtain a mixture. The mixture is coated on a side of the air transmitting layer and pressed by using a roller to obtain a product. The product is heated at 40-80 degrees C until an uniform sheet layer is obtained with a thickness of 0.1-3 mm to prepare an air reaction layer, followed by taking aluminum mesh, titanium meshes or steel mesh with aperture of 10-100 meshes as a current collector. The current collector, the air reaction layer and air transmitting layer are placed together from top to bottom using a hot press machine with pressure of 10-1000 Pa to prepare a lithium-air battery air electrode, followed by coating a metal lithium negative electrode by taking thin solid films, and liquid organic electrolyte, ionic liquid, colloidal, solid organic electrolyte as transition electrolyte. The transition electrolyte is coated on a surface of the solid film to form a double-layer electrolyte membrane that is pressed with a copper net of metal lithium negative electrode wrapped in double-layer electrolyte membrane. The metal lithium with double-layer electrolyte membrane is added with ionic liquid electrolyte, solid electrolyte membrane and air electrode in a battery shell to prepare a multi-layer electrolyte lithium air battery.
