Make battery core component more firm with diaphragm seal gluing between sealer while space；Again or, filling member can be in battery core component
Section components (as shown in Figure 3), for example, a part for the barrier film of battery core component, because barrier film has flexibility, in Fig. 3
The fold of Part I 121 of barrier film is placed between battery core component and diaphragm seal in space, to reduce battery core component and diaphragm seal
Between space while can play cushioning effect.Therefore, the lithium ion battery that the utility model embodiment is provided is by battery core
Filling member is provided between component and the first space of diaphragm seal, the sky between battery core component and the first space of diaphragm seal is reduced
Gap, effectively prevents battery core component opposing seal film from moving.And then make the battery core component opposing seal film more firm, it is to avoid due to electricity
The section components displacement of core assembly causes the phenomenon that inside lithium ion cell is short-circuited to occur.
Further, as shown in figure 3, filling member 4 described in above-mentioned utility model embodiment in battery core component every
From the Part I 1 of film 12.During specific implementation, the Part I 1 of barrier film 12 can be the end of the horizontal L of barrier film 12.
In actual applications, it is positioned over the first of diaphragm seal 2 after barrier film 12 is rolled along longitudinal direction (b directions as shown in Figure 4)
When in space, the end of the horizontal L of barrier film 12 is stretched out and is contradicted with the first space inner face of diaphragm seal 2.In other words every
The fold of Part I 1 from film 12 is placed in the first space, battery core component 1 is connected with the interference of diaphragm seal 2, to reduce battery core group
Gap between part 1 and diaphragm seal 2.When being subject to greater impact, battery core component 1 and diaphragm seal 2 in lithium ion battery drop event
Between be brought into close contact, be not easy to battery core component 1 and rocked in the first space, and then prevent the barrier film 12 in battery core component 1
Displacement makes the internal short-circuit of battery core component 1 obtain phenomenon generation.Explanation is needed exist for, the L correspondences in Fig. 2 to Fig. 5.
Further, with reference to shown in Fig. 3 and Fig. 4, the short circuit of battery core component internal is caused in order to prevent barrier film 12 from shrinking, on
Stating the battery core component 1 described in utility model embodiment includes barrier film 12 and electrode slice 11.Wherein, 11 points of electrode slice is for just
Pole piece and negative plate, positive plate and negative plate are respectively positioned at the opposite sides of barrier film 12.Barrier film 12 includes Part I 121
With Part II 122.The Part II 122 of barrier film 12 is consistent with the matching of the size of electrode slice 11.The Part I of barrier film 12
121 is the part beyond the Part II 122 of barrier film 12.Barrier film 12 is more than electrode slice 11 in the first dimension.Wherein,
Dimension be barrier film 12 when not being crimped, the horizontal L width of barrier film 12.Because barrier film 12 can be polyethylene film
Or polypropylene screen is made, with certain flexibility and it is heated and can produces contraction.Therefore, the utility model embodiment is by will be every
Size from film 12 is more than the size of electrode slice 11, and positive plate is contacted with negative plate and causes battery core after effectively preventing barrier film 12 from shrinking
Component internal short circuit.
In actual applications, size of the Part I 121 in the dimension of barrier film 12 first is at least 2.0mm, and isolation
Film 12 first space of the size more than diaphragm seal 2 of the first dimension in barrier film 12 (i.e. the of diaphragm seal 2 in the first dimension
The length in one space) size be 0.2-0.5mm.When the width of barrier film 12 is equal to the first space length size of diaphragm seal 2
When, due to the property of itself of barrier film 12, the bending size substantially 0.5mm of barrier film 12, that is, form 0.5mm spaces
Space, is easy to be subjected to displacement by greater impact in lithium ion battery drop event；When the width of barrier film 12 is more than sealing
During more than the first space length size 0.5mm of film 2, although can effectively reduce battery core component 1 empty with the first of diaphragm seal 2
Between between gap, but because the rich size of barrier film more than 12 is not easy to the first space that battery core component 1 loads diaphragm seal 2
It is interior, while increased cost causes the wasting of resources；When the first space length size of the width more than diaphragm seal 2 of barrier film 12
During 0.2-0.5mm, drawn through many experiments, it is empty with the first of diaphragm seal 2 that the size range can effectively reduce battery core component 1
Between gap, can make that cost is minimum again, practicality is higher.
