Description
Technical field
The invention belongs to a kind of generation of lithium battery production technical field more particularly to negative electrodes for lithium batteries collector dresses
It sets.
Background technique
It is positive electrode, negative electrode material, isolation film and electrolyte at four big major parts of lithium ion battery.But it removes
Main four is most of outer, and the collector for being used to store positive and negative pole material is also the important component of lithium battery.For lithium
For ion battery, usually used plus plate current-collecting body is aluminium foil, and negative current collector is copper foil, in order to guarantee collector in battery
Internal stability, the two purity are required 98% or more.With the continuous development of lithium power technology, it to be either used for digital product
Lithium battery or electric car battery, the energy density that we are intended to battery is high as far as possible, and the weight of battery is more and more lighter,
And main in collector this block is exactly the thickness and weight for reducing collector, intuitively reduces the volume and again of battery
Amount.
As lithium electricity was grown rapidly in recent years, lithium battery collector develops also quickly.Positive pole aluminium foil is by several years ago
16um is reduced to 14um, then arrives 12um, and volume production uses the aluminium foil of 10um to many cell production companies now, or even uses
To 8um.And cathode copper foil, since copper foil flexibility itself is preferable, thickness is reduced to 10um by 12um before, then arrives 8um,
To at present have significant portion battery producer volume production 6um and part of the manufacturer 5um/4um being developed be all possible to using
's.Since lithium battery is high for the copper aluminium foil purity requirement used, the density of material is substantially in same level, with exploitation thickness
Reduction, surface density also accordingly reduces, the weight of battery be naturally also it is smaller and smaller, meet us for the need of lithium battery
It asks.
Aluminium foil is mainly prepared with calendering process, and copper foil preparation method, mainly there is rolled copper foil and electrolytic copper foil two
Kind.The early stage of battery invention, due to the limitation of copper foil preparation process equipment and technology etc., the calendering copper of main higher operating costs
Foil, rolled copper foil are by copper sheet by rolling being repeated several times and manufactured former foil (being also hair foil), according to requiring to carry out at roughening
Reason.
At present in copper foil electrolysis process, first copper-bath is made through dissolution in copper first, then in dedicated electrolysis installation
It is middle by copper sulfate electrolyte under the action of direct current, electro-deposition and former foil is made, then according to require to former foil carry out surface
The a series of surface treatments such as processing, refractory layer processing and anti-oxidation processing.Electrolysis installation includes mainly titanium roller and anode plate,
Titanium roller segment is immersed in copper sulfate electrolyte, one layer of copper foil is generated in titanium roller surface by electrolysis process, then by subsequent
It handles and winds, when Faradaic current is constant, the velocity of rotation of titanium roller determines that copper foil generates thickness.Titanium roller continuous rotation is received
Winding apparatus is continuously wound, and can form continuously copper foil volume.But after titanium roller works long hours, titanium roller surface again is understood
There are contaminant particles or air floating layers, so that impurity is distributed in the copper foil surface generated, influence copper foil electric conductivity.In addition it gives birth to
At there are also flash phenomenons at copper foil edge.In addition, the length of titanium roller is certain, when needing to produce the titanium roller of different in width, need
The titanium roller of corresponding size length is replaced, it is very inconvenient.
Summary of the invention
In view of the above problems, the purpose of the present invention is to provide a kind of generating means of negative electrodes for lithium batteries collector, purports
In the skill that the copper foil surface that the existing copper foil generating means of solution obtain has impurity, has flash and can only produce fixed dimension copper foil
Art problem.
