PROBLEM TO BE SOLVED: To provide a method of manufacturing a lithium solid battery that has a high solid electrolytic membrane having Li ion conductivity and in which robust interface junction can be formed at both the surfaces of the solid electrolytic membrane.SOLUTION: A method of manufacturing a lithium solid battery comprises a film forming step of forming a CSE1 film formed of sulfide solid electrolyte material and containing no binding material on a positive electrode active material layer, and forming an ASE1 film formed of sulfide solid electrolyte material and containing no binding material on a negative electrode active material layer, by an AD (aerosol deposition) method, and a press step of pressing the CSE1 and the ASE1 while the CSE1 and the ASE1 are confronted to each other, thereby forming SE1 having the integrated CSE1 and ASE1. In the press step, the compactness of the CSE1 and the ASE1 is enhanced, thereby forming the SE1 in which the interface between the CSE1 and the ASE1 is extinguished.SELECTED DRAWING: Figure 1 |
