Definitions
- Embodiments of the present invention relate to a battery manufacturing method.
- a chargeable / dischargeable rectangular parallelepiped non-aqueous electrolyte battery such as a lithium ion battery is mainly used as a power source of an electric vehicle such as a hybrid electric vehicle and a plug-in electric vehicle which are rapidly spreading.
- a lithium ion battery is configured by housing an electrode group in which a positive electrode and a negative electrode are wound or stacked with a separator interposed therebetween, and a nonaqueous electrolyte, which are made of aluminum or an aluminum alloy, and in a rectangular parallelepiped case.
- a non-aqueous electrolyte battery such as a lithium ion battery
- moisture enters the battery during the manufacturing process and the internal pressure of the battery case increases due to gas generated by electrolysis of water. It was.
- the problem to be solved by the present invention is to provide a battery manufacturing method capable of suppressing the swelling of the exterior member.
- a battery manufacturing method including a liquid injection process, a first sealing process, a process including at least charging, a gas releasing process, and a second sealing process.
- the electrolytic solution is injected through a liquid injection port opened in the exterior member into the exterior member including the electrode.
- the liquid injection port is sealed.
- the gas release step a gas vent hole is opened in the exterior member, and the gas in the exterior member is released from the gas vent hole.
- the gas vent hole is sealed.
- FIG. 1 is an exploded perspective view of the battery according to the embodiment.
- FIG. 2 is a partially developed perspective view of the battery shown in FIG. 1 as viewed from below.
- 3 is a partially developed perspective view of an electrode group used in the battery shown in FIG.
- FIG. 4 is a top view of the battery shown in FIG.
- FIG. 5 is a cross-sectional view showing a gas releasing step for the battery shown in FIG.
- FIG. 6 is a cross-sectional view showing a second sealing step for the battery shown in FIG.
