Abstract

PURPOSE:To improve safety of thionyl chloride-lithium cell, by providing a safety valve device of thin-walled groove structure on the cell cover or the cell case. CONSTITUTION:A stainless steel top cover 2 is welded to a stainless steel case 1, also serving as the negative pole, of a thionyl chloride-lithium cell of spiral structure, the cover 2 being provided with a thin-walled groove portion 3 serving as a safety valve disposed thereon concentrically. The thin-walled groove portion is provided at the same time as the cover is formed by press work, and it is finished to the size, 0.2mm. wide and 0.02mm. thick, in the base matal being 0.4mm. thick. Therefore, the thin-walled portion readily breaks with the increase in the internal pressure to release the internal pressure to the outside. Further, the width of the groove, the thickness of the thin-walled portion, or the shape of the groove can be changed to preset the breaking pressure at a desired pressure value.

A partial enlarged cross-sectional view of part q is shown.The thin groove part in this example was created by press working at the same time as the battery cover was manufactured, and the standard thickness was Q.
2 #Shoulder and thickness are adjusted to Q and Q2a*. This J-like thin groove can be formed by a very nnI4a press process, and since it is thin, the mechanical strength of the product is low, and therefore it is easily distorted due to an increase in internal pressure. A rupture occurs in the same item, opening the inner king to the outside. In addition, the setting of the opening force is the groove width and the thickness of the thin part,
Alternatively, it can be easily changed by changing the shape of the groove.

In addition, the thin groove is not only provided on the battery cover, but also on the bottom of the case,
