The specific surface area of the positive electrode MATERIAL prepared by PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC is 0.4 ~ 0.9m2/g. However, the specific surface area of the ratio 4 is 3.5m2/g. In this technical field, the optimal range of the specific surface area of the positive electrode material is < 1m2/g. It can be seen that the co-precipitation method of the invention can make the specific surface area of the positive electrode material reach the optimal level in the field;
PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC field obtained positive electrode material vibration-solid density of 2.0 ~ 2.3g/cm3, compared with 1.8g/cm3, obviously better. The electrode sheet compaction density of the prepared positive electrode material is 3.1 ~ 3.4g/cm3, which is obviously better than 2.6g/cm3 for ratio 4. In this technical field, the optimal range of the electrode sheet compaction density parameter of the positive electrode material is > 3g/cm3, and the ideal value is 3.6 ~ 3.8g/cm3.
It can be seen that the PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC co-precipitation method can make the electrode plate compaction parameters of the positive electrode material reach the optimal level. The 0.1c, 1c and 50 cycle capacity retention rates of the positive electrode material are excellent. The positive electrode material has better performance.
