Sealed rectangular battery and manufacturing method for the same

摘要: A sealed rectangular battery has a conductive case including an external casing and sealing cap. The encloses generator element is by attaching the cap using heat. includes electrode terminal with opposite polarity to case, safety valve. valve that charged same as valving covers vent hole. are provided separately at different positions on case. This construction simpler than conventional batteries where integrally formed terminal, which means can be miniaturized. also improved internal resistance.
