    • A hermetically-sealed storage battery has a group of plates sheathed with a housing which is constituted by a synthetic resin film or sheet that is resistant to the electrolyte and is heat-weldable. Portions of the housing which surround the periphery of the group of plates are formed into a sealing portion by heat-welding together films or sheets of the type described above. A pair of terminal pieces protrude from the group of plates through the sealing portion. Part of the sealing portion is provided with safety valve which is constituted by an adhesion portion formed by portions of the films or sheets which are overlaid one upon the other. Thus it is possible to provide a hermetically sealed storage battery which has a simplified housing structure and which is capable of smoothly discharging any gas to the outside when there is an increase in the cell's internal pressure.
    • 气密式蓄电池具有由壳体护套组成的一组板,其由耐电解质且可热焊接的合成树脂膜或片构成。 通过将上述类型的薄膜或片材热焊接在一起,围绕该组板的周边的壳体的部分形成为密封部分。 一对端子片通过密封部从该组板突出。 密封部分的一部分设置有安全阀,安全阀由通过彼此重叠的膜或片的部分形成的粘合部分构成。 因此,可以提供具有简化的壳体结构的气密密封的蓄电池,并且当电池的内部压力增加时能够将任何气体顺利地排放到外部。
