In order to obtain more reversible capacity, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC can usually increase the content of nickel in the ternary material. For example, in ternary high nickel materials, when the molar content of nickel (molar content can represent the ratio of the number of a certain particle to the total number of particles of the same size of the substance) is increased to 82%, the ternary material 4.2V full battery capacity can reach 200mAh/g.
When the molar content of nickel is increased to 90%, the gram capacity of the ternary material 4.2V full battery can reach 205mAh/g. Synthesis method of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC precursor: Generally, the liquid phase co-precipitation method is used, with nickel sulfate (NiSO4), cobalt sulfate (CoSO4), manganese sulfate (MnSO4) as the reactant, water as the solvent, ammonia (NH3·H2O) as the complexing agent (ammonia complexing agent can dissolve impurities in the precipitation of ternary materials), and sodium hydroxide (NaOH) as the precipitating agent.
Taking the generation of NCM523 ternary material precursor as an example, the reaction equation is as follows:
0.5 NiSO4 CoSO4 MnSO4 + 0.3 + 0.2 + 2 and naoh Ni0.5 Co0.2 Mn0.3 (OH) 2 + Na2SO4
After dehydration and drying, the precursor powder can be obtained by removing iron from PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC field.
