NOVELTY - The method involves forming a conductive carbon layer (320) on a surface-treated inner surface of a pouch film (310) to form a negative electrode collector. A negative electrode layer (330) is formed on the conductive carbon layer to form a negative electrode plate. An adhesion/post-injection polymer electrolyte layer (200) is inserted between a positive electrode plate and the negative electrode plate to manufacture a battery assembly. An electrolyte e.g. aqueous electrolyte, is injected into the electrolyte layer. The battery assembly is completely sealed to form a primary battery.    USE - Method for manufacturing a flexible- polypropylene polymer-metal composite film vacuum-sealing-type primary battery for flexible ubiquitous terminals. Uses include but are not limited to a 1.5 volt film-type Manganese primary battery, 3 volt film-type primary battery, 1.5 volt open-type film and 3 volt pouch-type film battery, for scroll- type displays, electronic-papers, flexible LCDs, flexible organic LEDs (OLEDs) and wearable personal computers (PCs).    ADVANTAGE - The method enables adopting roll-to-roll process using screen printing process, thus facilitating automation, sequential fabrication and mass production and reducing manufacturing cost. The method allows the flexible-film primary battery to employ a pouch as a collector substrate so as to ensure flexibility and cut off transmission of gases and moisture, thus enabling manufacture of the sealing-type film battery. The method enables forming the collector with material, which can improve ductility of the collector, thus ductilizing the collector. The method enables surface-treating inner surfaces of the pouch so as to improve coating characteristics. The method enables using the polymer electrolyte layer including adhesion/post injection polymer matrix so as to improve cell safety. The method enables sealing the flexible-film primary battery under vacuum condition using thermal fusion technique, thus improving retention period, lifespan and safety characteristic. The method enables using the adhesion/post-injection layer including a porous core film, which is easily impregnated with electrolyte and polymer layers, which are coated on sides of the porous core film to be highly adhesive to the electrodes, thus facilitating performing sequential processes.    DETAILED DESCRIPTION - The adhesion/post-injection polymer electrolyte layer is a triple composite film.
