Description
Technical field
Field of battery production is the utility model is related to, more particularly to a kind of pole piece mends lithium device.
Background technology
With the development of modern society, battery turns into the maximum bottleneck of electronic product.Battery energy can be improved by mending lithium technique
Metric density, the battery capacity for avoiding the irreversible capacity due to battery during first charge-discharge from bringing reduce.
Existing benefit lithium technique is that lithium film is laminating in pole piece, and pole piece includes collector (being made up of metal foil)
And the coating coated in collection liquid surface；Between lug needs to be welded in collector, therefore the coating of collection liquid surface is typically
Have a rest coating, to reserve the clear area for tab welding on a current collector.But in lithium up process, lithium film can be by active lithium
It is laminating easily to cause tab welding bad in clear area, seriously it may cause fire in welding.
Utility model content
In view of problem present in background technology, the purpose of this utility model is that providing a kind of pole piece mends lithium device, its
It can realize that the interval of pole piece mends lithium, improve the security performance of pole piece.
To achieve these goals, the utility model provides a kind of pole piece and mends lithium device, and it includes roller press mechanism, pole piece
Conveying mechanism and lithium film conveying mechanism.Roller press mechanism includes two pressure rollers being oppositely arranged, and leaves gap between two pressure rollers；
Gap of the pole piece that pole piece conveying mechanism is used to drive lithium to be mended through two pressure rollers, and pole piece has collector and set
Put the coating in collection liquid surface；Lithium film conveying mechanism is used to drive gap of the lithium film through two pressure rollers.Wherein, two
The size in the gap between pressure roller is less than the thickness sum of lithium film, collector and coating, and more than the thickness of lithium film and collector
Spend sum.
The beneficial effects of the utility model are as follows：
In lithium device is mended according to pole piece of the present utility model, pole piece and lithium film are defeated in pole piece conveying mechanism and lithium film respectively
Send the gap through two pressure rollers under the drive of mechanism.When the coated areas of collector enters gap, due to two pressure rollers
Between gap size be less than lithium film, collector and coating thickness sum, so lithium film can be in the extruding of two pressure rollers
Under be attached on coating；And after the coated areas of collector passes from gap, pole piece and lithium film respectively in pole piece conveying mechanism and
Separated under the drive of lithium film conveying mechanism, and the lithium band on lithium film is retained on coating.And between entering when the clear area of collector
During gap, because the size in the gap between two pressure rollers is more than the thickness sum of lithium film and collector, so lithium film and collector
It will not be extruded by two pressure rollers, the lithium band on lithium film would not be also attached on collector.Therefore, pole of the present utility model
Piece, which mends lithium device, to mend lithium on the coating of pole piece, without mending lithium on a current collector, so as to realize that the interval of pole piece mends lithium,
Improve the security performance of pole piece.
