Battery Electrode Rolling Pressing Machine

Apr 22,2020

In order to improve the consistency of the density and thickness of the surface material of the battery electrode, the anode and cathode electrode must be rolled after the battery coating process. This process is called the battery rolling pressing of the battery electrode.

The purpose of electrode roll pressing is as follows:

1)Ensure that the surface of the electrode is smooth,and prevent burrs on the coating surface from puncturing the separator to cause short circuit.

2)Compact the coating material of the electrode and reduce the volume of the electrode to increase the energy density of the battery;

3)Make the active material and conductive agent particles contact more closely and improve the electronic conductivity;

4)Strengthen the bonding strength of the coating material and the current collector, reduce the occurrence of powder falling in the battery electrode during the cycle, and improve the cycle life and safety performance of the battery.

There are many influencing factors in the production process of lithium-ion batteries. After solving the process problems that may occur in each process, it will directly reduce the waste of production materials and improve the quality and efficiency of subsequent assembly, injection, packaging and other processes. Improve the quality and consistency of the final product, reduce production costs, and then make lithium-ion battery products more competitive in the market.

We are TOB New Energy, we are not only provide the equipment of the battery,but also provide the knowledge of battery.
