Definitions
- a side spacer 700 is disposed between the inner peripheral surface of the container 100.
- the side spacer 700 plays a role of regulating the position of the electrode body 400, for example.
- the side spacer 700 is formed of an insulating material such as PC, PP, PE, or PPS, for example, similarly to the upper spacer 500.
- the upper insulating member 125 is a member that electrically insulates the positive electrode terminal 200 and the cover plate 110 from each other.
- the lower insulating member 120 is a member that electrically insulates the positive electrode current collector 140 from the lid plate 110.
- the upper insulating member 135 is a member that electrically insulates the negative electrode terminal 300 from the lid plate 110.
- the lower insulating member 130 is a member that electrically insulates the negative electrode current collector 150 from the lid plate 110.
- the upper insulating members 125 and 135 may be called, for example, an upper gasket, and the lower insulating members 120 and 130 may be called, for example, a lower gasket. That is, in the present embodiment, the upper insulating members 125 and 135 and the lower insulating members 120 and 130 also have a function of sealing between the electrode terminal (200 or 300) and the container 100.
- the positive electrode current collector 140 is a member that is disposed between the electrode body 400 and the container 100 and electrically connects the electrode body 400 and the positive electrode terminal 200.
- the positive electrode current collector 140 is made of aluminum or an aluminum alloy.
- the positive electrode current collector 140 is electrically connected to the tab portion 410 on the positive electrode side of the electrode body 400 via a positive electrode lead plate 145 as a lead plate.
- the positive electrode lead plate 145 is formed of aluminum or an aluminum alloy as with the positive electrode current collector 140.
- the negative electrode current collector 150 is a member that is disposed between the electrode body 400 and the container 100 and electrically connects the electrode body 400 and the negative electrode terminal 300.
- the negative electrode current collector 150 is made of copper or a copper alloy.
- the negative electrode current collector 150 is electrically connected to the tab portion 420 on the negative electrode side of the electrode body 400 via a negative electrode lead plate 155 as a lead plate.
- the negative electrode lead plate 155 is formed of copper or a copper alloy.
- FIG. 11 to FIG. 15 are explanatory diagrams showing each process of bending the flat plate 800 according to the embodiment.
- the jig 900 and the jig 910 are retracted from the positions.
- the jig 900 is disposed on the opposite side of the tab portion 420 with the flat plate 800 interposed therebetween, the jig 900 does not come into contact with the tab portion 420 when retracted, and the tab portion 420 is not damaged.
- the negative electrode lead plate 155 having a U-shape in side view is described as an example.
- the shape of the lead plate is such that the first plate portion and the second plate portion face each other and they are integrated. Any shape can be used.
- 16 and 17 are side views schematically showing modifications of the lead plate according to the embodiment.
