AA negative electrode binder is a bonding material used in the preparation process of the negative electrode (also known as negative electrode current collector) of lithium-ion batteries. It is used to uniformly mix the active material, conductive agent, and binder and coat them on the current collector to form a good bonding and conductive network. AA adhesive usually refers to acrylic resin.

When making AA negative electrode, the following precautions should be taken:

1. Safe operation: When handling AA negative electrode adhesive, relevant safety operating procedures should be followed, personal protective equipment should be worn, and a well ventilated working environment should be ensured.

2. Adhesive formula: Choose a suitable AA negative electrode adhesive formula to ensure good viscosity, flowability, curing speed, and electrochemical stability, meeting the requirements of battery preparation process.

3. Uniform mixing: When preparing battery negative electrode materials, it is necessary to mix AA binder with active materials, conductive agents, etc. evenly to ensure the final formation of a uniform coating.

4. Coating process: When coating AA negative electrode binder, it is necessary to control the coating thickness and uniformity to avoid excessive or uneven coating affecting battery performance.

5. Curing conditions: According to the properties and preparation process requirements of AA binder, control the curing temperature, time, humidity and other conditions to ensure good curing of the binder and the formation of a stable negative electrode structure.

6. Environmental considerations: When using AA negative electrode binder, the impact of its composition on the environment should be considered, and binder materials that meet environmental standards should be selected, while strictly complying with relevant environmental regulations.


The above are some things to pay attention to when preparing AA negative electrode. Proper operation can ensure that AA binder plays a good role in the preparation process of lithium-ion batteries, while ensuring production operation safety and product quality.
