Abstract
The utility model relates to an insulation protection bag of an electrical core of a square lithium ion battery. The insulation protection bag is square, wherein the size of the insulation protection bag is equal to that of a cavity of a battery shell; all surfaces of the insulation protection bag are provided with a plurality of holes. The insulation protection bag disclosed by the utility model has the advantages of favorable insulation property, simple process and low cost and is beneficial to electrolyte absorption and electrical core heat dissipation during electrolyte injection; and the battery manufacturing procedure is simplified and the inconsistency among electrical cores, caused by human factors, is avoided.
Description
Technical field
The utility model relates to a kind of seal, is specifically related to a kind of insulation protection bag of electric core of rectangular lithium ion battery.
Background technology
Square lithium ion battery is a kind of battery of high-power high-capacity.In rectangular lithium ion battery, the insulation protection of electric core is extremely important, and its effect is that electric core and housing are isolated, and prevents electric core short circuit.Present insulation protection for such battery, several kinds of situation below normal employing the: the mode that adopts plastic film wrapped; The mode of insulation spacer and plastic film up and down; The mode of complete bag shaped structure; These insulation modes and all have problem to a certain degree, the aspects such as consistency of the heat radiation of the absorption of electrolyte, electric core, electric core when being mainly reflected in fluid injection.
The utility model content
For solving the problems of the technologies described above, the utility model patent provides a kind of insulation protection--poroid insulation protection bag of rectangular lithium ion battery electricity core.
The purpose of the utility model realizes through following technical scheme:
The insulation protection bag of a kind of rectangular lithium ion battery electricity core, said insulation protection bag is square, and the size of said insulation protection bag equals the inner cavity size of used battery container; Each face of said insulation protection bag all is provided with some holes.
The shape in hole can be square, strip, circle or other shapes.
Said insulation protection bag has following beneficial effect:
1, insulation property are good, the absorption of electrolyte and electric core heat radiation when also helping fluid injection.
2, the operation that battery is made, the inconsistency between the electric core of having avoided causing have been simplified because of human factor.
3, the technology of this protection bag making is simple, with low cost.
Description of drawings
Fig. 1: the utility model structural representation; Wherein, 1 hole.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Embodiment 1: with reference to Fig. 1, and the insulation protection bag of a kind of rectangular lithium ion battery electricity core, said insulation protection bag is square, and the size of said insulation protection bag equals the inner cavity size of used battery container; Each face of said insulation protection bag all is provided with some rectangular holes, and the rib of said insulation protection bag presents rectilinear form.
Said insulation protection bag adopts insulating material, and the electric core after the baking reinstalls housing after putting into the protection bag, has guaranteed the consistency of the elasticity of electric core.The absorption infiltration of electrolyte simultaneously, also helped the heat radiation of electric core when poroid around the protection bag helped fluid injection.
What should explain at last is: above embodiment is only in order to the technical scheme of explanation the utility model, but not to its restriction; Although the utility model has been carried out detailed explanation with reference to previous embodiment; Those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these are revised or replacement, do not make the spirit and the scope of each embodiment technical scheme of essence disengaging the utility model of relevant art scheme.
Claims (2)
