  Comparative analysis of dry and wet mixing technologies of lithium iron phosphate

  There are two main ways to mix lithium iron phosphate:

  (1) Dry mixing, mixing various materials in a dry powder state;

  (2) Wet mixing, put the insoluble raw materials into the ball mill according to the proportion, add water or other liquids for mixing.

  Wet mixing and ball milling is generally used in the laboratory. Its main advantages are uniform mixing and finer grinding. It can be granulated after ball milling. Many documents have compared the dry method and the wet method. The material properties prepared by the dry method are obvious. To be worse. However, in actual production, dry mixing is mostly used, mainly due to cost considerations. However, many problems such as material sticking to the pot or even forming hard lumps may occur during ball mill mixing.

  Reference technical route: Using iron oxide red, lithium dihydrogen phosphate, doping elements and carbon precursors as raw materials, the raw materials are activated and uniformly mixed at the molecular scale through liquid phase mechanochemical activation method and ultra-fine grinding, and the raw materials are used in sintering The pores created during the process control the production of crystals
