From the current technical level and product application situation, high nickel, high voltage, single crystal drive ternary cathode MATERIAL industry technology iteration, but also to ternary cathode material enterprises put forward higher PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC process difficulty: In the direction of high nickelization, the higher the nickel content, the higher the specific capacity under the same voltage condition.
When the radius of nickel ion is close to that of lithium ion, the possibility of cationic mixing in the structure is higher, which is easy to lead to the reduction of specific capacity of the material, the weakening of rate performance, and the reduction of surface stability of the material is more likely to cause safety problems. At the same time, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC process of more than 8 series of high nickel ternary positive material has special requirements for kiln equipment, sagger, reaction atmosphere, etc.
For PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC which involves secondary sintering or even more times, it is more difficult to ensure batch stability and consistency of products. At present, the industry mainly through doping, surface coating technology methods to modify the material, so that the high nickel ternary material in the thermal stability is enhanced at the same time to reduce the side reaction occurred in the process of application.
