2.1 Improving Battery Performance
By accurately rolling positive and negative electrode materials, the roller can effectively improve the pore structure of the material, reduce the porosity, and increase the volume energy density of the material. At the same time, the rolling process can also promote the close contact between the active substance and the collector, reduce the internal resistance, and improve the charge and discharge efficiency and cycle stability of the battery. These performance improvements have directly promoted the expansion of lithium batteries in electric vehicles, portable electronic equipment and other fields.
2.2 Improve production efficiency
The automated, intelligent lithium battery roller can achieve continuous and stable production operations, greatly reducing manual intervention and downtime. In addition, by precisely controlling the rolling parameters, multiple processes can be completed at one time, such as coating, drying, rolling, etc., effectively shortening the production cycle and improving the overall production efficiency. This is of great significance for reducing production costs and enhancing market competitiveness.
2.3 Promoting industrial upgrading
The wide application of lithium batteries to rollers not only promotes the continuous progress of lithium battery manufacturing technology, but also promotes the upgrading and integration of the entire industry chain. On the one hand, the innovation and development of roller technology has driven the technological innovation and product upgrading of upstream material suppliers; On the other hand, efficient and stable lithium battery production also provides more high-quality and reliable energy solutions for the downstream application market, and accelerates the rapid development of emerging industries such as new energy vehicles and energy storage systems.
