Abstract:
1. A method of manufacturing a flexible-film primary battery, comprising: providing a pouch comprising a first pouch film and a second pouch film; forming a first conductive carbon layer directly on a surface-treated inner surface of the first pouch film to form a positive electrode collector, and forming a positive electrode layer on the first conductive carbon layer to form a positive electrode plate; forming a second conductive carbon layer directly on a surface-treated inner surface of the second pouch film to form a negative electrode collector, and forming a negative electrode layer on the second conductive carbon layer to form a negative electrode plate; inserting an adhesion/post-injection polymer electrolyte layer between the positive electrode plate and the negative electrode plate to manufacture a battery assembly; injecting an electrolyte into the polymer electrolyte layer of the battery assembly; and completely sealing the battery assembly to form a primary battery, wherein the first pouch film includes a portion that extends from one side of the first pouch film and serves as a positive terminal, and wherein the second pouch film includes a portion that extends from one side of the second pouch film and serves as a negative terminal.
