Abstract
A kind of superpower infiltration bottom plastic structure for lithium battery, including a gummed paper, being covered with the gummed paper has micropore, there is the micropore for being available for electrolyte cross due to being covered with gummed paper, therefore, the electrolyte of housing bottom can be made to be penetrated into by gummed paper inside core, make core electrolyte inside sufficient, the lithium battery quality parameter improved.
Description
Technical field
It the utility model is related to a kind of superpower infiltration bottom plastic structure for lithium battery.
Background technology
At present, the core primer of lithium battery in-core is conventional gummed paper, and such gummed paper is installed to shell without permeability, battery core
After in vivo, because core primer is impermeable, cause housing bottom electrolyte effectively can not penetrate into core by core primer
Inside, the phenomenon for lacking electrolyte inside battery core electrolyte abundance but core be present, influence lithium battery quality parameter.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of to be oozed for the superpower of lithium battery
Reveal the exact details portion's plastic structure, it can make electrolyte cross.
The utility model is achieved in that a kind of superpower infiltration bottom plastic structure for lithium battery, including a gummed paper,
Being covered with the gummed paper has micropore.
Preferably, the material of the gummed paper is polypropylene.
Preferably, the thickness of the gummed paper is 50~60um.
Specifically, the thickness of the gummed paper is 55um.
Superpower infiltration bottom plastic structure provided by the utility model for lithium battery, it is available for due to being covered with gummed paper
The micropore of electrolyte cross, therefore, the electrolyte of housing bottom can be made to be penetrated into by gummed paper inside core, made inside core
Electrolyte is sufficient, the lithium battery quality parameter improved.
Brief description of the drawings
In order to illustrate more clearly of the technical solution of the utility model, below by the required accompanying drawing used in embodiment
It is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the utility model, for ability
For the those of ordinary skill of domain, on the premise of not paying creative work, it can also be obtained according to these accompanying drawings other attached
Figure.
Fig. 1 is the schematic diagram of the superpower infiltration bottom plastic structure provided by the utility model for lithium battery.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe.
As shown in figure 1, a kind of superpower infiltration bottom plastic structure for lithium battery that the utility model embodiment provides, bag
A gummed paper 1 is included, being covered with gummed paper 1 has the micropore 2 for being available for electrolyte cross, and micropore 2 is formed by double pull technologies.
Preferably, the material of the gummed paper 1 is polypropylene.
Preferably, the thickness of the gummed paper 1 is 50~60um, and the thickness of gummed paper 1 is 55um in the present embodiment.
Superpower infiltration bottom plastic structure provided by the utility model for lithium battery, due to being covered with gummed paper 1, have can
The micropore 2 that electrolysis liquid passes through, therefore, the electrolyte of housing bottom can be made to be penetrated into by gummed paper 1 inside core, make core
Electrolyte inside is sufficient, the lithium battery quality parameter improved.
Described above is preferred embodiment of the present utility model, it is noted that for the ordinary skill of the art
For personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these are improved and profit
Decorations are also considered as the scope of protection of the utility model.
