It not only directly affects the microstructure of the pole piece, thereby affecting battery performance, but also relates to the efficiency and quality control of the entire production process.

[0003] In the existing heating devices for lithium battery pole piece rolling mills, the heating mechanism of the lithium battery pole piece rolling mill mainly includes a heating plate fixed on the rolling mill. Heating is carried out through the flat heating plate. At positions adjacent to the upper and lower rolling rolls, the pole piece is directly heated. The heating plate is fixed adjacent to the rolling rolls in the pole piece feeding direction. By means of the flat heating plate, the contact area between the pole piece and the heating plate is increased, and the continuous heating time of the pole piece is extended, thereby improving the heating effect and the rolling quality of the pole piece.

[0004] However, this device has certain defects. When the distance between the rolling roll and the heating plate is fixed, the distance of heat transfer cannot be adjusted according to the actual situation, which may cause the pole piece to be overheated in some areas and underheated in other areas.
