摘要
以共沉淀为基础,主要研究了反应制备过程镍钴锰硫酸盐溶液、碱液、氨液的进料顺序和进料位置、进料管个数和进料温度对制备产品Ni0.55Co05Mn0.40(OH)2的影响.结果表明采用采用镍钴锰硫酸液、氨液、碱液的进料顺序;镍钴锰硫酸液上进料,碱氨液下进料;镍钴锰硫酸液和碱液两点进料、氨一点进料;镍钴锰硫酸液进料温度40～45 ℃可以合成较高性能的Ni0.55Co0.5Mn0.40(OH)2产品.
Abstract
Based on coprecipitation,in this paper,the effects of feeding sequence,feeding position,feeding tube number and feeding temperature of nickel-cobalt-manganese sulfate solution,alkali solution and ammonia solution on Ni0.55Co0.5Mn0.40(OH)2 were studied.The results show that Ni0.55Co0.5Mn0.40(OH)2 with high performance can be synthesized through method that Ni-Co-Mn liquid,ammonia liquid and alkali liquid as feeding sequence,Ni-Co-Mn liquid is fed up,alkali-ammonia liquid is fed down,Ni-Co-Mn liquid and alkali liquid are fed two points and 40-45 ℃ feeding temperature of Ni-Co-Mn solution.
