Description
Technical field
The invention belongs to the generation dress of lithium battery production technical field, more particularly to a kind of negative electrodes for lithium batteries collector
Put.
Background technology
The four big major parts into lithium ion battery are positive electrode, negative material, barrier film and electrolyte.But, remove
Main four are most of outer, the important component for being also lithium battery for the collector of depositing positive and negative pole material.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 ensure collector in battery
Internal stability, the two purity is required more than 98%.With continuing to develop for lithium power technology, either for digital product
Lithium battery or electric automobile battery, the energy density that we are intended to battery tries one's best height, and the weight of battery is more and more lighter,
And main in collector this block is exactly to reduce the thickness and weight of collector, intuitively the volume and again of battery is reduced
Amount.
With the electric fast development of lithium in recent years, lithium battery collector develops also quickly.Positive pole aluminium foil is by several years ago
16um is reduced to 14um, then to 12um, now many cell production companies volume production uses 10um aluminium foil, or even use
To 8um.And negative pole copper foil, due to copper foil pliability itself preferably, its thickness is reduced to 10um by 12um before, then to 8um,
To having significant portion battery producer volume production 6um at present, and the 5um/4um that part producer is developing is possible to use
's.Because lithium battery is high for the copper aluminium foil purity requirement used, the density of material is basic in same level, with exploitation thickness
Reduction, its surface density also accordingly reduces, and the weight of battery is naturally also less and less, meets our need for lithium battery
Ask.
Aluminium foil is mainly prepared from 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 technology equipment and technology etc., the higher calendering copper of main use cost
Paper tinsel, rolled copper foil is the former paper tinsel (being also hair paper tinsel) by rolling is repeated several times and is made by copper coin, is carried out as requested at roughening
Reason.
In current copper foil electrolysis process, first copper-bath is made through dissolving in copper first, then in special electrolysis installation
It is middle by copper sulfate electrolyte in the presence of direct current, electro-deposition and former paper tinsel is made, then as requested to former paper tinsel carry out surface
The a series of surface treatments such as processing, refractory layer processing and anti-oxidation processing.Electrolysis installation mainly includes titanium roller and positive 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 follow-up
Handle and wind, when Faradaic current is constant, the velocity of rotation of titanium roller determines that copper foil generates thickness.Titanium roller is continuously rotated, and is received
Winding apparatus is continuously wound, and can form continuously copper foil volume.But after titanium roller works long hours, understand titanium roller surface again
Leave contaminant particles or air floating layer so that impurity is distributed with the copper foil surface of generation, influence copper foil electric conductivity.It is raw in addition
Into copper foil edge also have flash phenomenon.In addition, the length of titanium roller is certain, when needing to produce the titanium roller of different in width, it is necessary to
The titanium roller of corresponding size length is changed, it is very inconvenient.
The content of the invention
In view of the above problems, it is an object of the invention to provide a kind of generating means of negative electrodes for lithium batteries collector, purport
The copper foil surface obtained in the existing copper foil generating means of solution has impurity, there is flash and can only produce the skill of fixed dimension copper foil
