摘　　要：探讨采用共沉淀法,提高三元金属液浓度和流量的情况下,制备三元正极材料LiNi0.8Co0.1Mn0.1O2的前驱体Ni0.8Co0.1Mn0.1(OH)2,通过扫描电镜分析、振实密度和比表面积测试,分析前驱体的物性数据。结果表明:提高三元金属液的浓度和流量,控制合适的反应条件,可得到形貌规则、比表面适中、振实密度高的前驱体产品。The preparation of cathode material LiNi0.8Co0.1Mn0.1O2 precursor Ni0.8Co0.1Mn0.1(OH)2 by coprecipitation with the case of increasing the concentration and flow of ternary metal liquid. The physical properties of precursors were analyzed by Electron microscope analysis, tap density and specific surface area test. The results of that when increasing the concentration and flow of the ternary metal liquid and controlling the appropriate reaction conditions, precursor products with regular morphology, moderate specific surface and high tap density can be obtained.
