Description

Technical Field

[0001] The utility model relates to the technical field of battery negative electrode material production, and more specifically, the utility model relates to a dryer for producing battery negative electrode materials. Background Art

[0002] A lithium-ion battery refers to a secondary battery system in which two different lithium-inserting compounds capable of reversibly inserting and extracting lithium ions are used as the positive and negative electrodes of the battery respectively. During charging, lithium ions are de-inserted from the positive electrode, pass through the electrolyte and separator, and are inserted into the negative electrode; during discharging, on the contrary, lithium ions are de-inserted from the negative electrode, pass through the electrolyte and separator, and are inserted into the positive electrode. The negative electrode of a lithium-ion battery is made by uniformly applying a paste adhesive made by mixing a negative electrode active material, a binder, and an additive on both sides of a copper foil, and then drying and rolling. There is a drying step in the production process of graphite negative electrode materials for lithium batteries.

[0003] However, at present, for a traditional material drying device for producing lithium battery negative electrode materials on the market, the drying efficiency is relatively low. Graphite is mostly directly placed in the drying device for drying. When a group of materials is being dried, the remaining materials can only wait for drying, and no drying treatment work can be carried out during the waiting period, resulting in a long drying waiting time and the problem that the drying efficiency cannot be improved.
