Abstract
The utility model provides an insulating piece of cylinder type lithium cell, belongs to the lithium cell field, and the purpose provides the insulating piece of cylinder type lithium cell that can make things convenient for anodal ear to go into position, reduction electrolyte penetration time, the technical scheme who adopts: it goes up insulating piece hole and anodal ear position holes upward to be equipped with six on the insulating piece to anodal ear position hole and anodal ear correspond settings, six go up in the insulating piece hole four upward insulating piece hole and the distribution of anodal ear position hole realize same, be equipped with a lower insulating piece hole and a central point negative pole earhole hole that the company is as an organic whole on the lower insulating piece, and central point negative pole earhole hole corresponds the setting with central point negative pole ear, upward insulating piece, lower insulating piece all adopt the preparation of PET material, the utility model discloses be applied to cylinder type lithium cell.
Description
Technical field
An insulation sheet for cylindrical lithium battery, belongs to field of lithium.
Background technology
Cylinder shape 18650 lithium ion battery is widely used in notebook computer, digital product, the fields such as power truck, research and development high safety performance, high cycle performance has become whole world focus, do on positive/negative plate and electrolyte ratio and material kind except considerable improvement, this body structure of lithium ion battery also causes the attention of people, a kind of cylindrical lithium ion battery is insulated sheet up and down, tradition insulation sheet easily produces following point: when positive pole Double-pole lug correspondence is not neat, neither meet anode ear and enter position, also the operating time is increased, uncertain in the face of what reel, its structure is not flexible, and existing structure adds the electrolyte permeability time, seriously have impact on production efficiency.
Practical novel content
The purpose of this utility model is to provide a kind of insulation sheet that anode ear can be facilitated to enter position, the cylindrical lithium battery of minimizing electrolyte permeability time.
For achieving the above object, the technical scheme that the utility model adopts: the insulation sheet of a kind of cylindrical lithium battery, comprise insulation sheet, lower insulation sheet, described upper insulation sheet is provided with six upper insulation sheet holes and an anode ear position hole, and the hole setting corresponding to anode ear of described anode ear position, described six upper four insulated in sheet holes upper insulation sheet holes and anode ear position hole distribution are on same circle, described lower insulation sheet is provided with lower insulation sheet hole and position, the center negative electrode lug hole that is connected as a single entity, and the setting corresponding to position, center negative electrode lug of position, described center negative electrode lug hole,
Described upper insulation sheet, lower insulation sheet all adopt PET material to make.
The thickness of described upper insulation sheet is set to 0.240mm～0.260mm; The thickness of described lower insulation sheet is set to 0.185mm～0.191mm.
The utility model compared with the existing technology has following useful effect:
One, by arranging the anode ear hole for anode ear at upper insulation sheet, make anode ear to enter position convenient, and what adjust anode ear flexibly by adjusting the size of anode ear hole enters position, greatly reduce the operation easier and operating time that reduce in producing;
By arranging, at upper insulation sheet, the sheet hole that insulate on six, vesicular structure can accelerate electrolyte permeability speed, reduces the fluid injection time of electrolytic solution, it is to increase production efficiency.
Two, by arranging position, the center negative electrode lug hole for negative electrode lug at lower insulation sheet, it is possible to meet the lithium ion battery demand of particular design.
Accompanying drawing explanation
Fig. 1 is lower insulation fin construction schematic diagram of the present utility model.
Fig. 2 be upper insulation sheet of the present utility model enter a schematic diagram.
Fig. 3 be lower insulation sheet of the present utility model enter a schematic diagram.
In figure, 2 is lower insulation sheet, and 21 is lower insulation sheet hole, negative electrode lug hole in position centered by 22.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1-Figure 3, the insulation sheet of a kind of cylindrical lithium battery, comprise insulation sheet, lower insulation sheet 2, described upper insulation sheet is provided with six upper insulation sheet holes and an anode ear position hole, and the hole setting corresponding to anode ear of described anode ear position, described six upper four insulated in sheet holes upper insulation sheet holes and anode ear position hole distribution are on same circle, described lower insulation sheet 2 is provided with lower insulation sheet hole 21 and position, the center negative electrode lug hole 22 that is connected as a single entity, and position, described center negative electrode lug hole 22 setting corresponding to position, center negative electrode lug;
Described upper insulation sheet, lower insulation sheet 2 all adopt PET material to make.
The thickness of described upper insulation sheet is set to 0.240mm～0.260mm; The thickness of described lower insulation sheet 2 is set to 0.185mm～0.191mm.
Working process of the present utility model is: be inserted in by position, the center negative electrode lug hole 22 of the sheet 2 that insulate under the negative electrode lug correspondence of position, center, and it is close to bottom the group of pole, first folding center position negative electrode lug, refolding edge negative electrode lug, make two lugs be in overlapping position, then pole group is put into box hat; Then corresponding for upper insulation sheet anode ear position hole anode ear is inserted in, and it is close to group top, pole.
Above-described embodiment is to explanation of the present utility model but not now; do not departing under not the utility model principle prerequisite the distortion done also within protection domain of the present utility model; the such as quantity of the anode ear position hole of adjustment upper insulation sheet, so that better permeating electrolytic solution.
