A manufacturing method for a flexible battery including injecting an electrolyte into an opening of an exterior material accommodating an electrode assembly contained therein and impregnating the electrode assembly with the electrolyte through a pressure difference inside the exterior material; and a sealing step of sealing the opening. Because the electrode assembly provided in the battery can be completely impregnated with an electrolyte, no spot occurs on the surface of a negative electrode filled with the electrolyte. In addition, the flexible battery can prevent or minimize deterioration of physical characteristics that the battery is required to exhibit, even if repeated bending occurs.

An electrochemical reactor includes positive and negative electrodes. A conductive and/or dielectric liquid is provided between the positive and negative electrodes. A first isolation member provided on the positive electrode isolates the positive electrode from the liquid, and a second isolation member provided on the negative electrode isolates the negative electrode from the liquid. The first and second isolation member each includes a liquid-repellent porous membrane. The reactor further includes a pressure-applying member which pressurizes the liquid to fill the pores of the first and second liquid-repellent porous membranes with the liquid, thereby causing an electrochemical reaction involving the positive and negative electrodes.

The present invention has an object to provide a secondary battery manufacturing method and apparatus capable of impregnating a sufficient amount of electrolyte in an electrode laminated body with simplified work effort while reducing working time and a manufacturing cost. The method of manufacturing a secondary battery according to the present invention comprises the steps of: inserting, into an outer container, an electrode laminated body in which a positive electrode and a negative electrode are laminated with a separator interposed therebetween; sealing an outer peripheral portion of the outer container except for a part thereof before or after the electrode laminated body is inserted; and injecting electrolyte (5) into the outer container having the electrode laminated body inserted therein, from non-sealed part as an injection port (6a). In the step of injecting the electrolyte (5), injection of the electrolyte (5) is started in an atmospheric pressure environment, and then the injection of the electrolyte (5) and pressure reduction of an environmental pressure are performed.
