摘要 以碳酸盐为沉淀剂,采用共沉淀法合成Ni1/3Co1/3Mn1/3CO3前驱体,再按照一定的锂配比将其烧结合成层状Li(Ni1/3Co1/3Mn1/3)O2。通过SEM及电性能测试仪等方法研究了碳酸盐前躯体的合成条件,考察了碳酸盐前躯体的振实密度与合成的pH值、溶液浓度以及反应时间的关系。经过实验分析,在pH=8、溶液浓度为2mol·L-1,反应时12~13h时合成的碳酸盐前躯体Ni1/3Co1/3Mn1/3CO3振实密度达到最高值0.98g·cm-3。 The precursor Ni1/3Co1/3Mn1/3CO3 was synthesized by carbonate co-precipitation,and then mixed it with certain LiOH.H2O. The layered Ni1/3Co1/3Mn1/3CO3 was obtained by high temperature solid state reaction. The powder was characterized by scanning electron microscopy (SEM). The synthesis condition ofprecrusor Ni1/3Co1/3Mn1/3CO3 was studied. The influences of pH, reactant concentration and reaction time on the density of precursor Ni1/3Co1/3Mn1/3CO3 were investigated.The resrlts showed that the density was the maximum when the pH=8-9, c= 2 mol .L^-1 and t= 12-13 h.
