Abstract

PURPOSE:To improve radiation efficiency for preventing a rise of battery inner temperature by providing a ventilation path on a lamination part of a thin type battery with a discharge fin. CONSTITUTION:A strip current collecting terminal is held on the upper terminal part provided with a collecting terminal having a notch part while a positive electrode active material 4 is held on the surface of a positive electrode collector 1 provided with a radiation fin 3 an the side end part and a sealing agent is arranged around this material 4. A thin type cell is formed by having a carbonaceous material on the front and rear sides of a similar negative electrode collector 7 having a radiation fin 11 or by making them to hold a negative electrode active material 8 consisting of lithium. Then, thin type cells are laminated through the frame bodies 12 and the lamination part is provided with a ventilation path 13. This constitution with a heightened radiation effect prevents a rise of a battery inner temperature and cuts off inferior thin type cells while the notch part of the positive electrode terminal serves as a fuse.

In the present invention, the current collector is provided with a band-shaped collector terminal (a part of which is provided with a cutout) at the upper end of the collector plate and a radiation fin at the side end of the collector to retain the active material in the center. A positive electrode current collector plate and a negative electrode current collector, each having a sealing agent on the periphery thereof, are laminated and sealed. In such a battery, since the heat radiation fins are arranged independently of each other and / or the ventilation passage is provided between the laminated batteries, it is possible to radiate heat without electrically shorting even if the battery temperature rises, and to integrate the batteries. A defective battery is separated by the partially missing portion of each of the collected current collecting terminals to prevent an abnormal temperature rise. Also, since they are independent of each other, they will not be reconnected with these debris. Further, by coating the tip of the terminal portion with zinc, tin-zinc, or tin-lead alloy, it becomes easy to connect them to each other. Further, since the above processing is continuously performed on the same electrode plate, it is possible to manufacture with high productivity.
