Abstract

The invention provides a lithium battery producing and processing device, and belongs to the technical field of lithium battery processing. The lithium battery producing and processing device comprises a barrel and a lifting screw; the lifting screw extends into the barrel, two L-shaped stirring rods are arranged on the lifting screw, a plurality of secondary stirring rods are arranged on the two stirring rods, a built-in pipe is arranged on the inner wall of the top of the barrel, and the lifting screw is located in the built-in pipe; and the built-in pipe is connected to the bottom of the barrel through a plurality of sets of supporting columns, and a plurality of sets of through holes are formed in the side wall of the built-in pipe. Rotation of the barrel is achieved through a first gear, a gear ring and a motor, rotation of the barrel and the stirring rods in the opposite directions is achieved through connection of a star following gear, the lifting screw and the stirring rods, the mixing and stirring effect is improved, slurry on the lower portion is pumped to the upper portion through the built-in pipe and the lifting screw, vertical circulation is conducted, and the mixing and stirring effects are further improved.

Description

technical field [0001] The invention belongs to the technical field of lithium battery processing, in particular to a lithium battery production and processing device. Background technique [0002] For the manufacture of electrodes of lithium-ion batteries, the positive electrode slurry is composed of binder, conductive agent, positive electrode material, etc.; the negative electrode slurry is composed of binder, graphite carbon powder, etc.; the preparation of positive and negative electrode slurry includes liquid and A series of technological processes such as mixing, dissolving, and dispersing between liquids, liquids, and solid materials, and this process is accompanied by changes in temperature, viscosity, and environment; in positive and negative electrode slurries, granular active materials Dispersion and uniformity directly affect the movement of lithium ions between the two poles of the battery. Therefore, the mixing and dispersion of the slurry of each pole piece m...
