Abstract
The utility model discloses a porous high temperature insulation adhesive tape that lithium ion battery used, including substrate, adhesive tape body, circular micropore. The adhesive tape body is vertical extension, bonds on the substrate through the glue film, and intermediate position department a plurality of circular micropores that are distributing uniformly, horizontal both ends fringe region does not set up circular micropore. Circular micropore does not pass the substrate. The utility model discloses the scheme is applicable to lithium ion battery, and the adhesive tape is high temperature resistant and the viscose stable, can play insulating protective action, can play well drain, air guide and heat conduction again.
Description
Technical field
The utility model is related to a kind of gummed paper, more particularly to a kind of porous high-temperature insulating cement suitable for lithium ion battery
Paper, belongs to lithium ion battery technology correlative technology field.
Background technology
At present, the high-temperature insulation gummed paper that lithium ion battery is adopted in industry, is non-porous gummed paper.With lithium ion battery skill
The development of art, while insulating protection effect is played, people are additionally contemplates that whether gummed paper can have certain leading to high tempreture tape
Permeability, can both ensure the infiltration of electrolyte, and the gas of inside battery generation and the conducting of heat are can guarantee that again.To meet lithium ion
This higher needs of battery, we have designed and developed a kind of porous high-temperature insulation gummed paper.
The 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, air guide and conductive force well can be played.
A kind of porous high-temperature insulation gummed paper, comprising base material 1, gummed paper body 2, circular micropore 3.The gummed paper body is in longitudinal direction
Extend distribution, be bonded on base material by glue-line, be dispersed with multiple circular micropore institutes, middle position is evenly distributed multiple
Circular micropore, transverse ends fringe region 4 is not provided with circular micropore 3.The circular micropore 4 is not passed through base material 1.
The base material 1 is the PET hyaline membranes of high tensile, and thickness is 50 ~ 100 μm.
The basement membrane of the 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 above-mentioned technical proposal, the present invention has compared with prior art advantages below：
The porous high-temperature insulation gummed paper of the present invention, it is micro- that the gummed paper body centre position is evenly distributed multiple circles
Hole.While playing insulating protection and acting on, the circular micropore arranged by gummed paper body is quickly by outside core for the gummed paper
Electrolyte permeability can improve fluid injection efficiency to inside core, first, the electrolyte that core outside second can be made full use of free,
And can quickly by the gas produced in inside battery and heat derives outside batteries, in the failure that can to a certain degree reduce battery.
Description of the drawings
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
Accompanying drawing is combined below by specific embodiment to be described in further detail the present invention.
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
State gummed paper body 2 to be distributed in Longitudinal extending；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 circular micropores 3；The gummed paper body transverse ends fringe region 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 of the present invention 1 adopts the PET film of high intensity so that gummed paper processing is simple, and quality can also have guarantor
Barrier.
2nd, gummed paper body 2 of the present invention is using high temperature resistant and electrolyte resistance type basement membrane and colloid, it is ensured that gummed paper is in electricity
There is higher heat endurance and chemical stability inside pond.
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.
It is quick by outside core by the circular micropore 3 arranged on gummed paper body 1 while so gummed paper can play insulating protection effect
The electrolyte permeability in portion can improve fluid injection efficiency to inside core, first, the electricity that core outside second can be made full use of free
Solution liquid, and quickly by the gas produced in inside battery and heat derives outside batteries to a certain degree can reduce battery
Failure.
4th, gummed paper body transverse ends fringe region 4 of the present invention is not provided with circular micropore 3, it is ensured that gummed paper is normal
When using, there is good tensile strength.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to the structure of 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.
