Preparation of high density Ni<i>0.5</i>Co<i>0.2</i>Mn<i>0.3</i>(OH)<i>2 </i>precursor body
In this thesis, we obtained Ni0.5Co0.2Mn0.3(OH)2 by controlling crystallization precipitation, and studyed the effect of the concentration of the material, ammonia dosage, pH, temperature, and so on other control parameters, and anti-oxidation technology, aging process, washing process on the microstructure, the bulk density, the average size and the degree of crystallinity and so on other properties of the sample. The experimental results showed that we can obtained nickel cobalt manganese acid lithium precursor Ni0.5Co0.2Mn0.3(OH)2 with the bulk density 1.75 g/cm3, good sphericitity, high crystallinitity, the large average size, narrow size distribution by optimizing the reaction parameters and improving process. By sintering of the precursor it shows that the precursor has stability structure, good sphericity and excellent performance.
