[0002] In the processing flow of electrode material, a crucial link is drying treatment. The purpose of this step is to completely remove the residual moisture inside the material, to avoid problems such as decomposition of electrolyte, corrosion of electrode material or internal short circuit of battery caused by moisture during battery operation, so as to ensure the performance stability and reliability of electrode material. Effective drying treatment plays a crucial role in improving the overall performance of lithium battery and prolonging its service life.

[0003] However, the existing electrode material drying equipment generally adopts a relatively traditional drying method when performing this key task, that is, heating the material cylinder loaded with electrode material.

This uneven heating problem not only affects the drying efficiency, but also may cause uneven stress distribution inside the electrode material, thereby causing a decline in material performance and even affecting the quality of the final lithium battery product.
