[0002] In the lithium battery production process, the applicability of the slurry directly affects the subsequent coating and the final battery performance, and is an important indicator for determining the battery cost. It can be said that slurry preparation occupies a core position in the lithium-ion battery production process.

[0003] Electrode slurry is a non-Newtonian fluid, which includes positive electrode slurry and negative electrode slurry, and is divided into oil-based and water-based systems. The stirred slurry needs to have good fluidity, stability and uniformity. Slurry viscosity that is too low or too high, sedimentation, agglomeration, uneven dispersion, etc., will have a great impact on subsequent coating and other processes, causing defects in the macroscopic appearance of the pole piece and inconsistency in the microscopic composition of the pole piece. Therefore, the motor slurry needs to be fully stirred before use during production.

[0004] After long-term use, the existing stirring device will have a certain amount of wear on the stirring rod and the stirring shaft, which will cause the subsequent stirring effect to deteriorate. However, the stirring shaft and the stirring rod of a general stirring device are fixedly connected. Once there is a problem with the stirring rod or the stirring shaft, the entire stirring mechanism needs to be removed for maintenance and replacement, which is very troublesome, wastes a lot of working time, reduces work efficiency, and has high maintenance costs.
