An invention relating to a method of manufacturing a solid electrolyte thin film of a fully solid Li-ion battery. In this method, a) preparing an electrically conductive substrate having a positive electrode film or a negative electrode film coated in advance, b) depositing an electrolyte thin film from the suspension of the electrolyte material particles by electrophoresis in the substrate and / or the previously formed anode or cathode film, c) drying the membrane obtained above, d) subjecting the electrolyte membrane obtained in the foregoing process to a coagulation treatment by mechanical compression and / or heat treatment. |
