Background

The current collector of a secondary battery such as a lithium ion battery refers to a structure or a part for collecting current, and in the case of the lithium ion battery, mainly refers to a metal foil such as a copper foil or an aluminum foil. The function of the current collector is to collect the current generated by the active materials of the battery so as to form a larger current output, therefore, the current collector should be in full contact with the active materials, and the internal resistance should be as small as possible.

In the prior art, the surface treatment of the conductive base material of the battery by using the functional coating is an important technical innovation, and the carbon-coated aluminum foil/copper foil is formed by uniformly and finely coating the dispersed conductive materials such as nano conductive graphite, carbon-coated particles, carbon nano tubes and the like on the aluminum foil/copper foil.

Application of carbon-coated aluminum foil to positive electrode current collectionThe interface contact impedance can be reduced, the internal resistance of the battery is reduced, the internal plan of the battery is lightened, and the discharge rate of the battery is improved to a certain extent. For the negative electrode of the lithium ion battery, the requirements of high surface density bonding performance of a high-energy density battery pole piece, easy-expansion silicon carbon material application, no powder falling of a laminated battery punching sheet and the like can be met by using the carbon-coated copper foil.

The existing carbon-coated foil surface functional coating is prepared by coating conductive slurry prepared by compounding conductive materials such as graphite, carbon black, multi-layer carbon nano tubes and the like, and uniformly dispersing the conductive slurry with dispersants and binders in different proportions on an aluminum foil or a copper foil and drying the aluminum foil or the copper foil. The preparation of the conductive paste needs to use high-efficiency dispersing and mixing equipment for nano, micron and other multi-scale particle size materials, and agglomeration of the materials is avoided, but the dispersing and mixing efficiency of the existing conductive paste is low, so that the materials with various particle sizes can not be efficiently and quickly mixed together, and the agglomeration of the materials can be completely avoided.
