Description
Technical field
The present invention relates to lithium ion battery manufacture field, burr is pulled out in particularly a kind of electrodes of lithium-ion batteries process
Except device and removal method.
Background technology
With 3C Product（Notebook, smart mobile phone, digital camera）, electric automobile extensive use, and energy-accumulating power station
Large scale construction, the also steady expansion year by year of lithium ion battery market scale, it is contemplated that market scale will be more than plumbic acid in 2018
Battery.
The manufacture of current lithium ion battery, when battery pole piece is cut, due to the upper and lower two knife registers angle of banding machine
The abrasion of deviation or the edge of a knife, produces burr easily at shearing.When burr length be more than membrane thicknesses when, easily pierce through every
Film, causes the short circuit between both positive and negative polarity, reduces battery qualification rate；Even if burr curtailment is to penetrate barrier film, but burr is long
（≥15μm）, then the self-discharge phenomenon of battery can be aggravated, influence battery performance.At present the membrane thicknesses specification that uses have 25 μm,
20 μm, 18 μm, 16 μm, 12 μm, with the raising that people are required battery energy density, increasingly tend to use it is relatively thin every
The membrane thicknesses that film, such as Huawei, i Phone battery are used are 12 μm, therefore, the burr of battery pole piece to battery qualification rate and
The influence of electric property is also more notable.
To solve this problem, the method attempted at present has Mechanical Method, chemical method, Physical etc..
In disclosed patent document, patent CN100521304C and patent CN203553272U use mechanical stitch,
First battery pole piece is fixed, restarts the edge that roller press rolls pole piece, unlike：The former utilizes the rounding of upper and lower roller
V notch v makes burr containing, and the latter makes burr containing using the acute angle that upper and lower not isometrical roller is formed, so as to avoid burr from penetrating
Barrier film.But these all do not remove flash removed, burr is simply set to bend inwards, in pole piece transhipment, go-no-go, the burr for bending inwards
Due to collision, extrude and outward bending again, the hidden danger of problem is still present, so the effect for eliminating burr is unsatisfactory, together
When discontinuous operation, be unsuitable for production application.
Equally, patent CN102350454B uses mechanical stitch method, although realize the continuity for the treatment of, but in pole piece point
When being wound after cutting, pole piece has a dynamic horizontal swing, simultaneously because burr is very small（10—50μm）, rolling position is slightly
Deviation may result in burr removal and not cut bottom or damage pole piece.
Also have using motor operation, such as patent CN201207403Y is carried out using high current, low-voltage on pole piece
Burr is melted by electric shock operation, the localized hyperthermia that transient current is produced, but aluminium fusing is needed to produce the high temperature of several Baidu, this meeting
Influence the activity of electrode material active principle., then there is secondary pollution and shadow in the chemical method that patent 200910036707.7 is proposed
Ring the problem of battery quality.
The content of the invention
