Description

technical field [0001] The invention relates to the technical field of production equipment for positive electrode materials of lithium batteries, in particular to processing equipment for positive electrode materials of lithium batteries. Background technique [0002] The main constituent materials of lithium-ion batteries include electrolyte, separator materials, positive and negative electrode materials, etc. The positive electrode material occupies a large proportion, because the performance of the positive electrode material directly affects the performance of the lithium-ion battery, and its cost also directly determines the cost of the battery. [0003] In the traditional process, the positive electrode material preparation method of lithium battery generally adopts the solid phase synthesis method, the process is simple, and the production conditions are easy to control. For example, to make positive electrode materials, various granular raw materials are mixed in p...

Problems solved by technology

However, there is discontinuity in this production method, its production efficiency is low, and it is difficult to adapt to large-scale production; in addition, the preparation process of lithium battery cathode materials in the traditional process generally uses feeding, mixing and reaction directly, and does not have Filtration and drying functions, which will lead to uneven mixing or too large particles will be directly put into the next process for reaction, which will not only affect the treatment process of the next process, but also affect the chemical properties of the lithium battery cathode material. Lithium battery cathode materials need to be stored in a dry environment, otherwise their performance will be seriously affected; in addition, current coolers are generally cooled by cold water, which has a poor cooling effect, and the cooled lithium battery cathode materials need to be dried before they can be replaced. It is well preserved, but the current dryer can only dry the surface, it is difficult to penetrate the surface material to process the lithium battery positive electrode material stacked in the middle, and the drying efficiency is low
