[0002] In the front-end process of lithium-ion battery production, the operation of the slurry mixing stage will directly affect the effect of subsequent coating and determine the cycle life, rate performance and safety performance of the battery; the slurry mixing operation generally refers to mixing, stirring and dispersing the electrode active material, binder, conductive agent and solvent in a certain proportion to obtain the slurry required for the electrode, and passing the slurry through a screening device. The slurry screening can remove the impurity particles in the slurry. After the slurry passes through the screen smoothly, the next stage of coating process can be carried out;

[0003] Before the production of lithium batteries, laboratory tests are conducted to effectively verify the manufacturing of the batteries. The screening device currently used in the test needs to be fixed at the four corners by four screws, but the screws are prone to loosening during the screening process, and the screen of the screening device cannot be clamped, causing the slurry to flow out from the side instead of being screened through the screen, which increases the screening time of the slurry. The slurry is exposed to the air and absorbs moisture, affecting the electrochemical performance of the slurry.

[0004] In addition, when replacing the screen, all the screws need to be unscrewed, which is inconvenient to operate, and the screws often rust and loosen, which can easily scratch your hands when replacing the screen. Utility Model Content
