The cathode material consists of a spheroid formed by a plurality of lamellar particles. Twelve sheet particles were selected for calculation, and the counterclockwise orientation Angle between their length direction and the set horizontal axis was measured with a progator. PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC field rotated the set horizontal axis within the range of [-π/2,π/2], and the maximum value was obtained through iterative calculation. The maximum value γ can characterize the consistency of orientation distribution of sheet particles of the positive electrode material.
When γ is the maximum value, the rotation Angle of the horizontal axis is set as δ. PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC field through iterative calculation, when δ = -0.2 radian is satisfied, γ is the maximum value 0.80. The closer the value of γ is to 1, the higher the consistency of orientation distribution of the flake particles. The smaller the γ, the more interlacing of single flake particles (the greater the difference between the length direction of multiple flake particles and the counterclockwise orientation Angle between the set horizontal axis);
The closer γ is to 1, the more obvious the consistency of orientation of a flake particle (the smaller the difference between the length direction of multiple flake particles and the counterclockwise orientation Angle between the set horizontal axis), PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC field after iron removal, γ = 1, It is equivalent to the state of parallel stacking of a flake particle and belongs to the most ordered state.
