Description

Technical Field

[0001] The utility model relates to the technical field of electrode positive electrode material preparation, in particular to an automatic coating mixing device. Background Art

[0002] At present, in the preparation process of battery positive electrode materials, in order to prevent the electrolyte from reacting with the materials, the materials are generally coated and modified. The production process will increase the process of "high-mix coating". Before coating, a variety of auxiliary materials are added and mixed with a small amount of base material to make a "premix". At present, most premixes are prepared by manually taking out part of the base material in advance, weighing a variety of auxiliary materials separately, and finally manually shaking and mixing them together. This method wastes a lot of manpower and material resources, and there is also the problem of uneven mixing of the premix. At the same time, after the premix is completed, the material is directly transported to the mixing pot along one inlet, which easily causes material accumulation. Utility Model Content
