Description
Technical field
The invention belongs to battery technology field more particularly to a kind of preparation sides of button cell diaphragm material diaphragm material
Method.
Background technique
Button battery is small in size, compact-sized, simple for production, in addition to being widely used in microminiature electronic product, and
The battery that vast scientific research person most often makes, for carrying out chemical property assessment to material, such as lithium ion battery plus-negative plate material,
High-ratio surface super capacitor material, lithium primary battery material etc..Cut out that size is suitable, diaphragm of Glabrous side can make
The performance performance of battery is best, reduces diaphragm and pollutes and influence to battery system bring.The tool for cutting diaphragm is led at present
There are scissors, cropping tool, slicer etc..But either scissors, cropping tool either sheet-punching machine, cut-out diaphragm side is more
It is coarse, rough, it will affect the performance of button cell performance to a certain extent, and sheet-punching machine involves great expense.Experiment at present
Lithium ion battery separator is cut using mechanical punching method in room and industrial production, this can cause certain impact to diaphragm, cause
Diaphragm is since unbalance stress is there are parts against wear, margin residual burr formation pollution sources, this for battery performance performance extremely
It is unfavorable.Meanwhile the problems such as tool for cutting lithium ion battery separator on the market at present involves great expense, and mold is easy to damage, it is also unfavorable
In the preparation cost for reducing lithium ion battery.
In addition, production button cell generallys use the polyalkene diaphragm of PP, PE etc, such diaphragm is very thin, flexibility
It is very good, damage diaphragm is easy to using the method for conventional mechanical punching.It is reported that vast researcher generallys use ball
Pen draws the circle of suitable size on diaphragm, then is shear off diaphragm along at mark with pocket knife or scissors, or purchase
Expensive diaphragm sheet-punching machine removes cutting diaphragm, but this method has shortcomings: 1) sharp nail, scissors, blade etc. are being cut
It is easy to damage diaphragm under shearing stress, leads to the battery short circuit of assembling；2) diaphragm sheared is non-round, and is easy to leave ball pen
Trace pollutes electrolyte；3) since the toughness of polyolefin macromolecular polymeric membrane is fabulous, shear history is clumsy, efficiency is very low
Under and edge roughness it is rough.4) also costly, mold design is also more accurate for slicer price.
Therefore, the method higher cost of existing production button cell, inefficiency, and pollution is easily caused to become ability
Field technique personnel technical problem urgently to be resolved.
Summary of the invention
In view of this, solving existing production the present invention provides a kind of preparation method of button cell diaphragm material
The method higher cost of button cell, inefficiency, and pollution is easily caused to become those skilled in the art's skill urgently to be resolved
Art problem.
The present invention provides a kind of preparation methods of button cell diaphragm material, comprising the following steps:
Step 1: metal needle being burnt on alcolhol burner flame red；
Step 2: metal disk is placed on diaphragm；
Step 3: being streaked with the processed metal needle of step 1 along metal disk edge, cut out the button of edge closed pore
Battery diaphragm material.
Preferably, the needle diameter of the metal needle is 0.5-1.5mm.
Preferably, the metal needle is electric iron or steel needle.
Preferably, the diameter of the button cell diaphragm material is 16-20mm.
Preferably, the metal disk is 16-20mm.
Preferably, the temperature of the alcolhol burner is 100-250 DEG C.
The preparation method of button cell diaphragm material provided in an embodiment of the present invention, compared with existing tailoring technique,
This method can make diaphragm edge Glabrous side, can effectively be scalded using the heat of steel needle institute band when contacting diaphragm wear every
Film, effective closed pore avoid when physics cuts cutting and damage diaphragm, while saving the slicer cost of expensive commercial, letter
The process that change prepares button cell.In addition, the present invention without using many and diverse automation equipment, only need simple heating tool with
Crop tool.Greatly reduce the preparation cost of lithium ion battery.
Specific embodiment
The following is a clear and complete description of the technical scheme in the embodiments of the invention, it is clear that described embodiment
Only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, the common skill in this field
Art personnel every other embodiment obtained without making creative work belongs to the model that the present invention protects
It encloses.
The embodiment of the invention provides a kind of preparation methods of button cell diaphragm material, solve existing production button
The method higher cost of battery, inefficiency, and easily cause pollution to become those skilled in the art's technology urgently to be resolved and ask
Topic.

1. material requested is alcolhol burner, metal needle or electric iron, diameter is 16-20mm metal disk (or coin), diaphragm.
2. metal needle is burnt on alcolhol burner flame red, about 100-250 DEG C of temperature, metal disk is placed on diaphragm, is used
Metal needle is gently streaked along metal disk edge, can cut out diameter about 16-20mm, edge closed pore and smooth diaphragm material
Material.
The preparation method of button cell diaphragm material provided in an embodiment of the present invention, compared with existing tailoring technique,
This method can make diaphragm edge Glabrous side, can effectively be scalded using the heat of steel needle institute band when contacting diaphragm wear every
Film, effective closed pore avoid when physics cuts cutting and damage diaphragm, while saving the slicer cost of expensive commercial, letter
The process that change prepares button cell.
In addition, the present invention without using many and diverse automation equipment, only needs simple heating tool and crop tool.
Greatly reduce the preparation cost of lithium ion battery.
The above is only a preferred embodiment of the present invention, it is noted that for making the professional technique of the art
