[0002] With the continuous development of the new energy industry, the market requirements for lithium battery products are getting higher and higher. The preparation of carbon coating slurry is an extremely critical link in the production process of lithium batteries. This process has relatively high requirements for the peel strength of the carbon coating layer.
