Abstract

PURPOSE:To enable a battery to be formed concurrently small and thin, by forming a small hole and a projecting part in a part of film or sheet which covers a group of electrode plates and bending the projecting part to cover the small hole and partially performing thermal welding on its bent part and then injecting silicon oil into the gap, so that a safety valve can be formed. CONSTITUTION:A small hole 3 and a projecting part 4 are formed in a film or sheet 1, and the projecting part 4 is bent to cover the small hole 3. After thermal welding 5 is performed partially on its bent part, silicon oil is injected into the gap hiding the small hole 3 by using a 6 or the like. While another film or sheet 1' is overlapped thereon,thermal welding 5' is performed on its periphery and a group of electrode plates 7 are inserted therein. A cover 8 equipped with terminals 2 are jointed with the films or sheets 1, 1' by thermal welding, adhesion, or the like to form a battery. A battery can be formed concurrently thin and small.

Problems to be Solved by the Invention It is difficult to automate the mounting of the valve body with such a cap-shaped rubber valve body, and due to limitations in the processing accuracy of the valve body, it is necessary to make the valve part smaller and thinner. It was difficult. In order to solve this problem, as shown in Fig. 7, a structure has been proposed in which the electrode plate group is wrapped in a synthetic resin film 10, and some unwelded parts are left around the periphery, and silicone oil 9 or the like is injected into these parts to form a valve. C
(Japanese Unexamined Patent Publication No. 59-207558). However, although this structure allows the valve to be made thinner, since the valve is located on the outer periphery of the battery, it increases the projected area of the battery, which is disadvantageous for miniaturization.

Means for Solving the Problems In order to achieve this object, the safety valve of the present invention has a small hole and a protrusion in a part of the film or sheet covering the electrode plate group, and the small hole is formed by bending the protrusion. After heat welding a portion of the cover, silicone oil is injected into the gap to form the valve.

As a result, the safety valve can be provided not on the outer periphery of the battery but in a position overlapping the electrode plate group, so the space required for the safety valve can be minimized, making it possible to make the battery thinner and smaller at the same time. .
