High speed dispersing equipment, slurry, battery pole piece and lithium ion battery

Abstract

The invention belongs to the technical field of slurry preparation and battery preparation, particularly relates to high speed dispersing equipment, slurry, a battery pole piece and a lithium ion battery. The high speed dispersing equipment comprises a dispersing barrel and a dispersing wheel which are coaxially arranged, wherein the dispersing wheel is positioned in the dispersing barrel; the dispersing barrel comprises a side wall provided with a spiral track, and the spiral track is positioned on the inner surface of the side wall; the dispersing wheel comprises a barrel and holes, a plurality of tooth-like bumps are formed on the outer surface of the wall of the barrel, and the holes are of frustum structure and are arranged in the barrel wall. The dispersing capacity of the equipment for the slurry can be effectively improved as a result of the design. Inner substances of the slurry prepared by using the equipment are more uniformly dispersed, so that the agglomeration phenomenon of the active substances is remarkably mitigated. The battery pole piece prepared by using the slurry has smaller impedance, so that the electric property of the lithium ion battery prepared by using the slurry or the electrode pole piece is obviously improved.

Description

technical field

[0001] The invention belongs to the technical field of slurry preparation and battery preparation, and in particular relates to a high-speed dispersion device, a slurry, a battery pole piece and a lithium ion battery. Background technique

[0002] Lithium-ion batteries have gained popularity in modern society because of their advantages such as high voltage, large specific energy, long cycle life, good safety performance, low self-discharge rate, no memory effect, wide operating temperature and a certain degree of fast charge and discharge capabilities. Wide range of applications. The existing industrial production process of lithium-ion batteries is usually: pulping, coating, assembly and chemical formation. Among them, the quality of the pulping process directly affects the performance of the positive and negative electrode materials, which in turn determines the performance and quality of the finished battery. The standard to measure the quality of the p...
