Abstract
The invention discloses a porous high-temperature insulation gummed paper for a lithium ion battery, comprising a base material, a gummed paper body, and circular micropores. The gummed paper body is extended longitudinally and bonded on the base material through a glue layer; a plurality of circular micropores are evenly distributed at the middle position, and the circular micropores are not arranged at the edge zones of both ends in cross direction. The circular micropores do not pass through the base material. The scheme of the invention is applicable to lithium ion battery, the gummed paper is high-temperature resisting and stable in bonding; the gummed paper can play the insulation and protection effects as well as the good liquid, gas and heat conduction effects.
Description
Technical field
The present invention relates to a kind of gummed paper, particularly to a kind of porous high-temperature insulation gummed paper being applied to lithium ion battery, belong to
In lithium ion battery technology correlative technology field.
Background technology
At present, the high-temperature insulation gummed paper that in industry, lithium ion battery adopts, is atresia gummed paper.With lithium ion battery skill
The development of art, while playing insulating protection effect, people are additionally contemplates that whether gummed paper can have certain leading to high tempreture tape
Permeability, both can ensure the infiltration of electrolyte, can guarantee that the gas of inside battery generation and the conducting of heat again.For meeting lithium ion
This higher needs of battery, we have designed and developed a kind of porous high-temperature insulation gummed paper.
Content of the invention
For above-mentioned technical problem, it is an object of the invention to provide one kind can play insulating protection effect, and
The porous high-temperature insulation gummed paper of drain, inducing QI and conductive force well can be played.
A kind of porous high-temperature insulation gummed paper, comprises base material 1, gummed paper body 2, circular micropore 3.Described gummed paper body is in longitudinally
Extend distribution, be bonded on base material by glue-line, be dispersed with multiple circle micropore institutes, middle position is evenly distributed multiple
Circular micropore, transverse ends marginal area 4 is not provided with circular micropore 3.Described circle micropore 4 is not passed through base material 1.
Described base material 1 is the PET hyaline membrane of high tensile, and thickness is 50 ~ 100 μm.
The basement membrane of described gummed paper body 2 is PET or PI or PP, and colloid is acrylic glue or silica gel.
The thickness of described gummed paper body 2 is 20 ~ 50 μm.
The bore dia of described circular micropore 3 is 0.5 ~ 2.0mm.
Due to the utilization of technique scheme, the present invention compared with prior art has advantages below：
The porous high-temperature insulation gummed paper of the present invention, described gummed paper body centre position is evenly distributed multiple circle micropores.Should
, while playing insulating protection effect, the circular micropore being arranged by gummed paper body is quickly by the electrolyte outside core for gummed paper
Penetrate into inside core, first can improve fluid injection efficiency, second can make full use of free electrolyte outside core, and can be fast
Speed by the gas producing in inside battery and heat derives outside batteries, in the inefficacy that to a certain degree can reduce battery.
Brief description
Fig. 1 is the structural representation of the present invention.
In accompanying drawing：1st, base material；2nd, gummed paper body；3rd, circular micropore；4th, gummed paper body edges at two ends region.
Specific embodiment
Combine accompanying drawing below by specific embodiment the present invention is described in further detail.
As shown in Fig. 1, the porous high-temperature insulation gummed paper of the present invention, including base material 1, gummed paper body 2, circular micropore 3；Institute
Stating gummed paper body 2 is in that longitudinal extension is distributed；Described gummed paper body 2 is bonded on base material 1 by glue-line；Described gummed paper body
1 centre position is evenly distributed multiple circle micropores 3；Described gummed paper body transverse ends marginal area 4 is not provided with circular micro-
Hole 3；Described circular micropore 3 is not passed through base material 1.
The advantage of the high-temperature insulation gummed paper of the porous of the present invention is as follows：
1st, base material 1 of the present invention adopts the PET film of high intensity so that gummed paper processing is simple, and quality can also be secure.
2nd, gummed paper body 2 of the present invention adopts high temperature resistant and electrolyte resistance type basement membrane and colloid it is ensured that gummed paper is in electricity
There are higher heat stability and chemical stability inside pond.
The 3rd, the circular micropore 3 of multiple a diameter of 0.5 ~ 2.0mm is evenly distributed on gummed paper body 2 of the present invention.
While so gummed paper can play insulating protection effect, by the circular micropore 3 of setting on gummed paper body 1 quickly by outside core
The electrolyte permeability in portion, to inside core, first can improve fluid injection efficiency, second can make full use of free electricity outside core
Solution liquid, and to a certain degree can reduce battery quickly by the gas producing in inside battery and heat derives outside batteries
Lost efficacy.
4th, gummed paper body transverse ends marginal area 4 of the present invention is not provided with circular micropore 3 it is ensured that gummed paper is normal
During use, there is good tensile strength.
Embodiment described above is only that the preferred embodiment of the present invention is described, the not structure to the present invention
Think and protection domain is defined, on the premise of without departing from design concept of the present invention, technical scheme is made
Various modifications and improvement, all should fall into protection scope of the present invention.
