Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery production, in particular to a battery slurry filtering device. BACKGROUND

[0002] In the process of battery production, the preparation of battery slurry is a crucial step, which directly determines the electrochemical performance, safety and consistency of the battery. The slurry is usually prepared by uniformly mixing active material, conductive agent, binder and dispersion medium (such as deionized water or NMP solvent) in a specific ratio. The preparation process needs to be carried out in a strictly controlled environment, through high-speed stirring, dispersion and other processes to ensure that each component is highly uniform and free of agglomeration, so as to form a stable and suitable flowability slurry. The final prepared slurry needs to have appropriate viscosity and solid content to meet the requirements of subsequent coating process, to ensure the uniformity of the electrode sheet surface density and strong adhesion, thereby laying a solid foundation for producing high-capacity, long-life and high-safety lithium ion batteries.

[0003] In the production process of battery slurry, filtration is a key process to ensure the purity of materials and remove large particle agglomerates and impurities. In this process, if the temperature of the slurry is too high, it will have a series of negative effects on its physicochemical properties and the performance of the final battery. High temperature will accelerate the volatilization of solvents (such as NMP or water) in the slurry, resulting in a significant increase in slurry viscosity and poor flowability. This not only increases the difficulty and energy consumption of filtration, but also may cause the filter mesh to be blocked too quickly, reducing production efficiency, and even causing equipment scaling due to dry slurry. High temperature may affect the stability of the binder (such as PVDF). SUMMARY
