PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC magnetic preparation process does not use sodium carbonate, sodium carbonate role is: In the process of co-precipitation, carbonate ions are uniformly doped in the co-precipitation lattice, which improves the morphology and agglomeration mode of hydroxide co-precipitation, reduces the nucleation rate of hydroxide, increases the number of pores of precursor, facilitates the complete diffusion of sodium ions in the sintering process, and gets the positive electrode of sodium ions with high solid density.
First, the primary particles are longer and thicker, which can increase the orientation order degree of the primary particles, and the γ value is higher. Then, it can be seen that for materials with the same composition, the vibration density increases with the addition of sodium carbonate. PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC field has better specific surface area, vibration density, electrode compacting density and electrical properties.
The preparation of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC field does not use reducing agent to inhibit the oxidation of fe2+, which can prevent excessive small particles from being produced and prevent the gap between dv10 and dv90 from being too large. First of all, the spheroid α value is higher, indicating that the size distribution between the particles is not uniform, and then the prepared positive electrode material has better specific surface area, vibration density, electrode plate compaction and electrical properties.
