The particle size distribution parameter of the positive electrode material, β is the average value of the ratio of the long axis length to the short axis length of the spheroid in the particle size distribution range of dv50. n is the number of flake particles selected for calculation of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC magnetic removal process on spheroids within the size distribution range of dv50, n≥10; θi is the anticlockwise Angle between the length direction of the selected i flake particle and the set horizontal axis.
δ is the horizontal axis of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC magnetic process rotation set in the range of [-π/2,π/2]. The rotation Angle relative to the set horizontal axis when γ is maximized. The oxygen content in sintering atmosphere is more than 21%. The continuous flow rate of sintering atmosphere is 5l/h ~ 50l/h. The sintering pressure is 0.1mpa ~ 0.5mpa.
The sintering temperature is 700℃ ~ 950℃. The sintering time is 5h ~ 20h. For PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC process, the first solution of 2mol/l is 4l. A second solution containing 4mol/l naoh and 0.2mol/l sodium carbonate was prepared. A third solution 4l containing 5g/l ammonia water and 0.2ml/l hydrazine hydrate was prepared;
