Description

Technical Field

[0001] This utility model relates to the field of lithium battery cathode material mixing technology, specifically a lithium battery cathode material mixing device. Background Technology

[0002] Mixing is a crucial step in the manufacturing process of lithium-ion battery cathode materials, and the mixing effect is one of the important factors determining the material performance. Improving mixing efficiency and shortening the production cycle have become a key focus for lithium-ion battery cathode material companies. Currently, lithium-ion battery cathode material mixers employ advanced mixing technologies, such as high-speed stirring, centrifugal mixing, and bidirectional rotary mixing. These technologies can quickly and uniformly mix the cathode materials, improving mixing efficiency and significantly shortening mixing time.

[0003] However, considering the actual situation of the production line, there is a problem of rough material temperature control. In particular, the material temperature control during the overall process of material mixing is relatively rough and does not meet the level of intelligence of lithium battery cathode materials. There is an optimal mixing temperature range during the coating and mixing of materials and additives. Exceeding this temperature range will reduce the coating effect and affect the material performance. Therefore, a lithium battery cathode material mixing device is proposed. Utility Model Content
