In order to improve the safety of the secondary battery, a method for producing the secondary battery using a solid electrolyte is under study. However, the process of producing an all-solid-state secondary battery by stacking the electrodes and the solid electrolyte separately after making them separately is not only complicated, but also due to the residual moisture between the electrodes and the solid electrolyte. It is possible to cause a reaction. Also, an additional step is required to reduce the interfacial resistance between the electrode and the solid electrolyte. In the present invention, in order to eliminate such a drawback, a mixed slurry of a conductive ceramic substance and a polymer mixed with a solvent is applied to the electrode, the solvent is evaporated, and then the liquid electrolyte is absorbed, and the opposite is true. An integrated all-solid-state secondary battery is manufactured by covering the electrodes. These integrated all-solid-state secondary battery fabrication methods have the effect of simplifying the fabrication stage, suppressing side reactions, and reducing the interfacial resistance between the electrode and the solid electrolyte.
