Abstract
A battery container 10 includes a case member 1, one side of the case member 1 being opened, and a closing member 2 for closing the opening. Further, a material-shortage section 24 is formed near a welding section 13, the case member 1 and the closing member 2 being brought into contact with each other and welded in the welding section 13 by irradiating the welding section 13 with a welding beam. Further, the case member 1 is welded with the closing member 2 so that the welding section 13 reaches the material-shortage section 24. Note that a width of the material-shortage section 24 in a welding beam irradiation direction may be equal to or greater than one third of a fusion depth of the welding section 13.
Claims11
A battery container comprising:
- a case member, one side of the case member being opened;
- and
- a closing member for closing the opening, wherein
- a material-shortage section is formed near a welding section, the case member and the closing member being brought into contact with each other and welded in the welding section by irradiating the welding section with a welding beam, and
- the case member is welded with the closing member so that the welding section reaches the material-shortage section.
A manufacturing method of a battery container formed by joining a case member whose one side is opened with a closing member for closing the opening by welding, the manufacturing method comprising:
- forming a material-shortage section near a welding section, the case member and the closing member being brought into contact with each other and welded in the welding section by irradiating the welding section with a welding beam, and
- performing the welding so that the welding section reaches the material-shortage section.
