The density of negative electrode coating surface is unstable.

Hello, what is the reason for the unstable surface density of negative electrode coating? The reasons for the unstable surface density of the negative electrode coating are as follows:

1. Improper control of coating process: Improper setting of coating process parameters may lead to unstable coating surface density.

2. Poor uniformity of the coated cloth: If the uniformity of the coated cloth itself is not good, the density of the coated surface will be uneven.
