Abstract
The utility model discloses a porous cylindrical lower gasket of a lithium ion battery. The porous cylindrical lower gasket comprises a round gasket with a central round hole in the center, a square groove hole in the edge and a plurality of micropores in other parts. The insulated lower gasket favorable for absorbing an electrolytic solution at the bottom of a steel shell by battery cells can fully utilize the electrolytic solution at the bottom of the steel shell while achieving an insulation effect.
Description
Technical field
The utility model relates to a kind of technical field of lithium ion, has related to the parts of inside lithium ion cell, relates in particular to a kind of Round Porous column type lithium ion battery lower gasket.
Background technology
At present, cylindrical lithium ion battery is in the process of fluid injection, box hat bottom all has a certain amount of unabsorbed electrolyte, and these electrolyte parts are slowly absorbed by battery core in the process of circulation, there is chemical reaction and be wasted in part, thereby need to improve the in use absorption to bottom electrolyte and utilization of battery core.The lower gasket thickness of existing various cylindrical lithium ion batteries is thicker, be generally between 0.13mm ~ 0.35mm, and pad, except the square notch at centre bore and edge, does not have other micropore, obviously affects battery core absorbing bottom electrolyte.
Summary of the invention
The purpose of this utility model is to provide a kind of Round Porous column type lithium ion battery lower gasket, is conducive to the insulation lower gasket of battery core absorption box hat bottom electrolyte, and this pad is thinner, and it can make full use of the electrolyte of box hat bottom in playing insulating effect.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of Round Porous column type lithium ion battery lower gasket, comprises pad, and pad is circular, it is characterized in that: circular hole centered by the center of pad, and the edge of pad is provided with square slotted eye, and multiple micro-holes are distributing in the other parts of pad.
According to described Round Porous column type lithium ion battery lower gasket, it is characterized in that: the thickness of described pad is 0.09mm-0.11mm.
According to described Round Porous column type lithium ion battery lower gasket, it is characterized in that: the material of described pad is the polymer composite of insulation.
The utility model has the advantages of and be: be conducive to the insulation lower gasket of battery core absorption box hat bottom electrolyte, this pad, in playing insulating effect, can make full use of the electrolyte of box hat bottom.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In accompanying drawing: 1, square slotted eye; 2, micro-hole; 3, center hole.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figure 1, a kind of Round Porous column type lithium ion battery lower gasket, comprises pad to the utility model, pad is circular, it is characterized in that: circular hole 3 centered by the center of pad, the edge of pad is provided with square slotted eye 1, and multiple micro-holes 2 are distributing in the other parts of pad.According to described Round Porous column type lithium ion battery lower gasket, it is characterized in that: the thickness of described pad is 0.09mm-0.11mm.According to described Round Porous column type lithium ion battery lower gasket, it is characterized in that: the material of described pad is the polymer composite of insulation.
As shown in Figure 1, the material of first selecting processing is macromolecular material high temperature resistant, corrosion-resistant, insulation to service condition of the present utility model, and this material can resistance to 250 ℃ of high temperature, indeformable under the immersion of electrolyte.Pass through Mould Machining, pad after processing is circular gasket, there is the center hole 3 of certain size at its center, there is a square notch 1 at circular edge, pad is that center has a circular port, gasket edge has a square notch, removes centre bore and square notch, and other solid face of pad is uniform-distribution with the micro-hole of 1mm.Box hat bottom electrolyte is easier to be penetrated into battery core surface by micro-hole like this, is absorbed by battery core.The thickness of the final processing of this pad is 0.1mm, and the thinner battery core that can be battery of pad is economized out a bit available space.
Embodiment recited above is described preferred implementation of the present utility model; not design of the present utility model and protection range are limited; do not departing under the prerequisite of the utility model design concept; various modification and improvement that in this area, common engineers and technicians make the technical solution of the utility model, all should fall into protection range of the present utility model.
Claims (3)
