One-step solid phase PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC magnetic method usually uses transition metal/metal salts and sodium uniformly mixed for high temperature solid phase sintering, which has the characteristics of simple process and low cost, but the shape and size of the material are uncontrollable, and the batch stability of the material is poor.
A mixed solution of water-soluble salt, water-soluble salt and water-soluble salt was prepared, which was recorded as solution, and the total concentration of metal ions in the solution was 95g/ L-105g /l; Prepare a solution of ammonia water with a concentration of 25%-30%, which is recorded as a solution; The preparation of a solution with a concentration of 16%-20% is recorded as a solution; Under the conditions of 350rpm-400rpm and 50℃-60℃, the solution was added to the PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC reactor to obtain the bottom solution with ammonia concentration of 4g/ L-8g /l and ph of 11.5-11.8.
The solution was added into the PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC reactor at the rate of 8l/ H-12L /h, 0.8l/ H-1.5L /h and 2.0l/ H-2.8L /h respectively, and the ph of the reaction system was controlled to be 10-11. Coprecipitation reaction was performed; When the product reached the target particle size, the reaction was ended, and the hydroxide precursor was obtained after separation and drying.
