Abstract
The invention discloses the method for lithium ion battery coating lamination Electrostatic Absorption pole piece antistatic breakdown barrier film, the underface that electrostatic transmitting bar is placed on barrier film produces electrostatic to barrier film, pole piece is placed on barrier film by coating laminating machine, barrier film utilizes Electrostatic Absorption pole piece, and anti-static device is added between electrostatic transmitting bar and barrier film.Advantages of the present invention：Anti-static device is added between barrier film and electrostatic transmitting bar are, the electrostatic potential that the intensive place of needle point of electrostatic transmitting bar is too high is transmitted on anti-static device, reflected through anti-static device, and spread from the surrounding of anti-static device, then it is transmitted on barrier film, anti-static device is placed in the effective travel of electrostatic transmitting bar, Electrostatic Absorption positive plate can be produced to barrier film, so that relative position of the packaging positive plate on barrier film is constant, and can prevents barrier film is breakdown from damaging the short circuit for causing battery core pole group, short circuit ratio is reduced within 3% between 10% 30% and keeps stable state.
Description
Technical field
The present invention relates to a kind of method of antistatic breakdown barrier film, more particularly to a kind of lithium ion battery coating lamination electrostatic
The method for adsorbing pole piece antistatic breakdown barrier film, belongs to technical field of lithium batteries.
Background technology
Due to increasingly deficient and common people's environmental consciousness the enhancing of the energy, lithium battery is because green, safety is without dirt
The advantages that dye, increasingly favored by market.The battery core pole group of lithium battery needs positive plate and negative plate in process of production
Successively it is stacked alternately, adjacent positive plate and negative plate are separated with film, then are tied up neat pole group is stacked, traditional
Traditional laminating machine uses machinery positioning, can to caused by positive plate secondary damage, and in moving process positive plate on barrier film
Relative position malleable, influence battery performance, new coating laminating machine is made that improvement on traditional laminating machine, and positive plate is put
In diaphragm, while electrostatic transmitter is placed on the underface of barrier film and produces a large amount of electrostatic to barrier film, utilizes the super of positive plate
The property led is together with barrier film generation Electrostatic Absorption, so as to ensure that relative position of the positive plate on barrier film is constant.This improves rule
Machinery positioning secondary damage to caused by positive plate is kept away, the simplification of mechanism also reduces cost.But due to barrier film below
Electrostatic transmitting bar be needle point launch electrostatic structure, during use the intensive place of needle point because electrostatic potential it is too high and unstable, can go out
Barrier film breakdown damage is now caused to cause the short circuit of battery core pole group, before not taking Improving Measurements, the short circuit ratio of battery core pole group is in 10%-
Fluctuation is, it is necessary to spend substantial amounts of manpower to be done over again, waste of material is larger between 30%.
The content of the invention
The technical problem to be solved in the present invention, be to provide a kind of lithium ion battery coating lamination Electrostatic Absorption pole piece prevent it is quiet
The method of electrical breakdown barrier film, this method are to add anti-static device between barrier film and electrostatic transmitting bar are, apparatus structure letter
Single, easy to make, cost is low, directly can effectively prevent electrostatic breakdown barrier film.
The present invention is realized by following proposal：Lithium ion battery coating lamination Electrostatic Absorption pole piece antistatic breakdown barrier film
Method, the underface that electrostatic transmitting bar is placed on barrier film produce electrostatic to barrier film, and pole piece is placed on barrier film by coating laminating machine
On, barrier film utilizes Electrostatic Absorption pole piece, and anti-static device is added between electrostatic transmitting bar and barrier film.
The anti-static device is copper sheet.
The thickness of the copper sheet is 0.1mm-1mm.
The anti-static device is placed in the effective travel of the electrostatic transmitting bar.
Needle point 20mm more than of the anti-static device apart from the electrostatic transmitting bar.
Needle point 20mm of the anti-static device apart from the electrostatic transmitting bar.
The anti-static device is in contact with the metal part of the equipment after ground connection.
Evenly distributed multiple width are 20-30mm engraved structure on the copper sheet.
Beneficial effects of the present invention are：Anti-static device, electrostatic transmitting bar are added between barrier film and electrostatic transmitting bar are
The too high electrostatic potential in the intensive place of needle point be transmitted on anti-static device, reflected through anti-static device, and from anti-static device
Surrounding diffusion, be then transmitted on barrier film, anti-static device is placed in the effective travel of electrostatic transmitting bar, can give barrier film
Produce Electrostatic Absorption positive plate so that relative position of the packaging positive plate on barrier film is constant, and and can prevents the breakdown damage of barrier film
Wound causes the short circuit of battery core pole group, and short circuit ratio between 10%-30% from being reduced within 3% and keeping stable state, on copper sheet
It is even to arrange the engraved structure that multiple width are 20-30mm so that too high electrostatic potential is transmitted into after anti-static device through anti-
Penetrating can spread uniformly.
