Problems solved by technology

Different battery products have different production parameters in the pole piece manufacturing process. The length of different types of battery pole pieces such as square products, soft package products, and cylindrical products need to be designed and then coated. The pole piece is a large pole piece with spacing, so it has a negative impact on product development and resource utilization
