PURPOSE:To increase the fixing strength and the freedom degree on design of a current collecting mesh for a current collecting electrode, and prevent the deterioration of flatness of the current collecting electrode by itself so as to enhance liquid tightness. CONSTITUTION:A photosetting resin is applied to a copper plate of a predetermined area, and a portion of the copper plate except for a mesh pattern baked by photoetching is removed, thus obtaining a current collecting mesh 6. The current collecting mesh 6 and carbon plastic electrodes 15a, 15b, 15c are laminated, followed by integrally molding by a heat-press means, thereby obtaining an electrode unit 19. The electrode unit 19 is locally fused in a suitable portion inside a hole 17 formed on a sheet-like insulating frame member 16 provided with a terminal piece taking-out slit 14, thus providing current collecting electrode taking-out structure of a zinc-bromine battery. A terminal piece fusing portion 20a is formed at the center of the current collecting mesh 6, and then, a terminal piece 6a is fixingly fused or screwed to the terminal piece fusing portion. |
