In the coating application of positive and negative electrode materials, the film coating machine can realize high-precision, effective and high-consistency film preparation. Positive and negative electrode materials are mainly used in lithium-ion batteries, solar cells and other fields, and film coating machines play an important role in their preparation process.
Membrane method
The coating film preparation method of positive and negative electrode materials mainly includes the following steps:
Preparation of materials: According to the required formula, mix the materials evenly in a certain proportion;
Prepare the coating stock solution: add the material mixture to an appropriate amount of solvent, and fully mix it in a magnetic stirrer to form a coating film stock solution;
Coating machine coating: use a film coating machine to evenly coat the coating stock solution on the substrate to form a thin film;
Drying treatment: place the coated substrate in a Drying Oven for proper drying treatment to remove residual solvent and moisture;
Baking treatment: according to the specific requirements and process, the dried film is baked to obtain the required electrochemical performance.
In the preparation process of positive and negative electrode materials, the coating machine is mainly used for coating, including the coating of anode materials, cathode materials and electrolyte. The film coating machine has the characteristics of high precision, high speed and high repeatability, which can achieve accurate coating thickness and uniformity, and improve the quality of coating film and production efficiency. The film coating machine can also realize automatic control to improve the controllability and consistency of the preparation process.
