Pyrolysis process: the intermediate material is put into the reactor, under an inert gas atmosphere and a certain pressure, according to a certain temperature curve for electric heating, stirring at 200~300℃ for 1-3h, and then continue heating to 400-500℃, stirring to obtain the material with a particle size of 10-20mm, cooling discharge, that is, the intermediate material. PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC. PTMS Lithium Cobalt acid material magnetic.
Ball mill screen division order: vacuum feeding, the intermediate MATERIAL is transported to the ball mill for mechanical ball milling, 10~20mm material is ground into 6~10 micron particle size material, and the intermediate material is screened, and the iron is removed by PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC. The material on the screen is transported by the pipeline vacuum back to the ball mill for ball grinding again. The size, distribution and morphology of graphite particles affect many properties of anode materials.
In general, the smaller the particles, the better the rate performance and cycle life, but the worse the first efficiency and compaction density (which affect the bulk energy density and specific capacity), and vice versa, and the reasonable particle size distribution (mixing large and small particles), PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC (after removing iron) can improve the specific capacity of the negative electrode; The morphology of the particles also has a great influence on the magnification and low temperature performance.
