As a ternary positive electrode MATERIAL, energy storage NCM523 is used. Usually, the processing technology of ternary positive electrode material PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC is mainly based on the production process of nickel-cobalt-manganese ratio of 5:3:2, taking nickel-cobalt-manganese lithium 523 as an example. The development of ternary cathode materials all know that the benefits of nickel-cobalt manganese oxide lithium inherit the advantages of lithium nickelate and lithium cobalt oxide advantages. The stability of the cathode material is N times higher than that of lithium nickelate, but the energy density is also much higher than that of lithium cobaltate. Therefore, taking nickel-cobalt-manganate lithium anode material as an example to explain the production process of cathode material has representative significance.
High nickel ternary materials need to be broken to the micron level after calcination, usually need to undergo three-stage crushing, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC removal of iron. At present, the commonly used crushing system in industry is jaw crushing - roll crushing - air crushing, and the particle size is from 1 to 20μm. After grading and screening, D50=10μm grade particles are generally selected as semi-finished particles in industry.
The semi-finished product after the particle grading of high nickel ternary MATERIAL needs to be cleaned by PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC, and the metal magazine introduced in the process is removed, generally based on iron, and magnetic separation is usually used in industry to remove iron. The particles after impurity removal are vacuum-packed to form the finished particle of the positive electrode material.
