There are several types of wrinkling of the lithium battery electrode sheets, the wavy edge of the lithium battery electrode, the wrinkle of the lithium battery electrode, and the wrinkling of the paint area. Of course, there are several degrees of wrinkling severity. Wrinkles in the coating area of the electrode will cause the surface of the bare cell to be uneven, and the stress conce...

The current collector is one of the indispensable components in lithium-ion batteries. It can not only carry active substances, but also collect and output the current generated by electrode active substances, which is beneficial for reducing the internal resistance of lithium-ion batteries, improving the Coulombic efficiency, cycle stability, and rate performance of batteries. At present, the pos...

Coating process is a process based on the study of fluid properties, which involves coating one or more layers of liquid onto a substrate. The substrate is usually a flexible film or backing paper, and then the coated liquid coating is dried in an oven or cured to form a special functional film layer. The coating process of lithium-ion power battery electrodes has its own characteristics: d...
