    摘要： According to the present disclosure, technology of preventing reduction of battery performances in manufacturing steps is provided for a secondary battery provided with a protective member for preventing cleavage of a welded part. A secondary battery disclosed herein includes an electrode body including a terminal connecting part, an exterior body including a welded part at an outer circumferential edge part, and an electrode terminal connected with the terminal connecting part. The secondary battery includes a protective member that is placed between the exterior body and the electrode body, and regulates shrinkage deformation of the exterior body toward a center in a width direction. The second battery further includes a movement regulating means for regulating movement of the protective member. This can prevent reduction of battery performances in manufacturing steps.

    摘要： A battery includes a casing that has an inner surface defining a chamber for an electrolyte, and a conductive lining being configured for electrical communication with a first battery terminal. There is also a permeable separator sheet disposed between the electrolyte and the conductive surface; a conductive rod having a first end configured for electrical communication with a second battery terminal, and, a second end configured for contacting the electrolyte. There is also an opening disposed in the casing; a sealing member configured for arrangement between at least a sealed position and an unsealed position to allow a potential difference to be produced between the first and second battery terminals. There is also at least one spacing element configured for spacing the electrolyte apart from the conductive lining within the chamber.
