Method.
Background technology
, it is necessary to carry out two envelopes after current polymer lithium ion battery cell chemical conversion, two envelope processes extract the gas inside battery core out,
And by airbag side carry out hot-press sealed, then airbag sideline judge is cut away, after the completion of carry out next procedure operation.Operated at this
Cheng Zhong, while also can extraction section electrolyte.In the prior art, the amount for extracting electrolyte out mainly adds different levels by pad
What cardboard was controlled, but the operation has still had following deficiency：1）Operation difficulty is big, control accuracy is low；2）Concora crush
Mode easily causes electrolyte and spread from center to corner, causes electrolyte at battery core corner to accumulate to be formed " rise liquid ", and influence is outer
See；3）Cardboard is running stores, is difficult recycling, causes waste of material and not environmentally.
Therefore, the method for accuracy of measurement is possessed it is necessory to provide a kind of improvement battery core electrolyte.
The content of the invention
It is an object of the invention to：In view of the shortcomings of the prior art, a kind of improvement battery core electrolyte recoverable amount essence is provided
The method of degree, this method can lift battery core electrolyte and possess accuracy of measurement, improve the outward appearance of battery core.
To achieve these goals, the present invention uses following technical scheme：
It is a kind of to improve the method that battery core electrolyte possesses accuracy of measurement, comprise the following steps：
Step one, silicagel pad is close to the bottom of the top board of two envelope equipment；
On step 2, the base that the battery core for treating secondary encapsulation is positioned over to two envelope equipment；
Step 3, adjusts the position of silicagel pad, starts two envelope equipment；
Step 4, silica gel pad position is adjusted in battery core width back and forth, realizes the accurate control to electrolyte recoverable amount；
Wherein, the silicagel pad is in the rectangle that is projected as of the top board, and the thickness of the silicagel pad is along the silicagel pad
Width gradual change successively from left to right, the airbag of the battery core is arranged at the less side of silica gel mat thickness.
Compared to Paper Based Bolster Plate of the prior art, silicagel pad of the invention has advantages below：
1）Silicagel pad has certain pliability, is conducive to pressure to be more uniformly distributed；
2）When top board is pressed downward, silicagel pad most thick one side touches the non-airbag side of battery core first, by electrolyte from non-
The lateral airbag side extruding of airbag one, can effectively solve the accumulation situation of battery core corner position electrolyte, improve battery core outward appearance；
3）Can be by adjusting the relative position of silicagel pad and battery core in width, to change the pressure that battery core is subject to, so that more
Electrolyte extracted amount is accurately controlled, regulative mode is simple；
4）Silicagel pad can be recycled, cost-effective；
5）Silicagel pad can meet most battery core model demands, wide using window.
The a kind of of method for possessing accuracy of measurement as improvement battery core electrolyte of the present invention improves, the silicagel pad
Thickness is 0.2 ~ 5mm.
The a kind of of method for possessing accuracy of measurement as improvement battery core electrolyte of the present invention improves, the silicagel pad
Length value is more than the length value of the battery core.
The a kind of of method for possessing accuracy of measurement as improvement battery core electrolyte of the present invention improves, the silicagel pad
Width value is more than the width value of the battery core.
The beneficial effects of the present invention are：The present invention provides a kind of method that improvement battery core electrolyte possesses accuracy of measurement, bag
Include following steps：Step one, silicagel pad is close to the bottom of the top board of two envelope equipment；Step 2, will treat secondary encapsulation
Battery core is positioned on the base of two envelope equipment；Step 3, adjusts the position of silicagel pad, starts two envelope equipment；Step 4, in battery core
Width adjusts silica gel pad position back and forth, realizes the accurate control to electrolyte recoverable amount；Wherein, the silicagel pad is described
Top board is projected as rectangle, the width gradual change successively from left to right of the thickness of the silicagel pad along the silicagel pad,
The airbag of the battery core is arranged at the less side of silica gel mat thickness.Relative to prior art, the present invention can be carried effectively
Rise battery core electrolyte and possess accuracy of measurement, and improve the outward appearance of battery core.
