To this, utilize Fig. 3 to do and illustrate.Fig. 3 uses current collection parts 70 along the figure of the narrowed width of direction A, C for explanation is anodal with current collection parts 60 and negative pole.In addition, positive pole is identical shapes with current collection parts 60 and negative pole with current collection parts 70.Therefore, describe as representative with current collection parts 60 with positive pole.
The right side of Fig. 3 shows the stereogram of the positive pole use current collection parts 60 of the present embodiment.The left side of Fig. 3 shows and the positive pole different current collection parts 100 of current collection parts 60.Current collection parts 100 have and the positive pole slightly identical shape of current collection parts 60, comprise first, second curren-collecting part side connecting portion 101,102 and body 103.Body 103 has the bight 104 identical with bight 75, and 104 places are crooked in the bight.
For current collection parts 100, it is different from positive pole and with current collection parts 60 parts is: along the orientation of first, second electrode part side connecting portion 101,102, the length of body 103 is fixed.That is, for body 103, be not 104 to diminish towards the bight along the length of the orientation of first, second electrode part side connecting portion 101,102, but fixing.
On the current collection parts 100 in left side, the positive pole current collection parts 60 of the present embodiment have been represented with chain-dotted line in Fig. 3.So, the positive pole of the present embodiment, can make along the narrowed width of first, second electrode part side connecting portion 61,62 orientations on the whole with respect to current collection parts 100 with current collection parts 60.
As shown in the left side of Fig. 3, for positive pole with current collection parts 60, can with along the width of direction A for fixing plate member, when representing that with chain-dotted line part is blocked, 65 bendings in the bight and making.This point is equally applicable to negative pole current collection parts 70.At this, positive pole is not limited to current collection parts 100 are made in the mode of chain-dotted line part excision with current collection parts 70 with current collection parts 60 and negative pole.Anodal with current collection parts 60 and the negative pole sheet material with the body 63 of current collection parts 70,73 profile with having respectively, 65,75 part bendings in the bight and form also harmless.
With current collection parts 60 along the narrowed width of direction A the time, therefore negative pole can suppress battery 10 short circuits with current collection parts 70 narrowed width along direction C due to positive pole.This is described as follows.For positive pole with current collection parts 60 and negative pole with current collection parts 70, when first 66,76 65,75 is not when narrowing down along the width of direction A, C towards the bight, will keep wide state along the width of direction A, C.
If there is load to be input to battery 10 from the outside, this load can be passed to electrode part 30.If anodal is wide shape with current collection parts 70 along the width of direction A, C as mentioned above with current collection parts 60 and negative pole, load easily is passed to anodal current collection parts 60 and the negative pole current collection parts 70 used.
Be delivered to positive pole and use the load of current collection parts 70 with current collection parts 60 and negative pole, if enough can make greatly positive pole current collection parts 60 and negative pole current collection parts 70 distortion, positive pole current collection parts 60 and negative pole current collection parts 70 generation distortion so.
Use the variation of current collection parts 70 as positive pole with current collection parts 60 and negative pole, its edge part is recessed in electrode bundle 31.If take this kind distortion, can imagine that so battery 10 is short-circuited when laminal anodal 32 and laminal negative pole 33 when damaged.
But, the battery 10 of the present embodiment, for positive pole with current collection parts 60 and negative pole for current collection parts 70, its first 66,76 65,75 narrows down towards the bight gradually along the width of direction A, C.And second portion 67,77 is kept along the width of direction A, C with bight 65,75 along the width of direction A, C.That is, second portion 67,77 keeps along direction A, C width the state that narrowed down.
Therefore, even there is load to be delivered to battery 10, this load also is difficult to be delivered to anodal with current collection parts 60 and negative pole current collection parts 70.That is, positive pole is difficult to deform with current collection parts 70 with current collection parts 60 and negative pole, therefore can suppress the anodal short circuit of using the caused battery 10 of distortion of current collection parts 70 with current collection parts 60 and negative pole.
So, by making the anodal narrowed width of using current collection parts 70 with current collection parts 60 and negative pole, can suppress anodal and produce distortion with current collection parts 60 and negative pole with current collection parts 70, therefore need to not deform with current collection parts 70 with current collection parts 60 and negative pole and be used for improving the rigidity of housing 20 or the reinforced structure of intensity in order to prevent positive pole, or not needing reinforced structure is carried out strong, the cost that therefore can suppress battery 10 improves.
The present invention is not limited to previous embodiment itself, in implementation process, does not break away from the scope of its aim, can carry out conversion and be specialized inscape.In addition, more than providing by the reasonable combination previous embodiment, an inscape, can form various inventions.For example, the several inscapes of deletion are also harmless from whole inscapes that aforesaid embodiment provides.
