摘　　要：探讨采用共沉淀法,在使用浓密机提浓的情况下,制备三元正极材料LiNi0.8Co0.1Mn0.1O2的前驱体Ni0.8Co0.1Mn0.1(OH)2,以提高三元前躯体的物理性质。实验结果表明:浆料经浓密机浓缩重新返回反应釜反应,多次循环后,前驱体粒度增大,颗粒均匀,形貌规则,比表面积小。Explore the use of co-precipitation method to prepare the precursor Ni0.8Co0.1Mn0.1(OH)2 of the ternary cathode material LiNi0.8Co0.1Mn0.1O2 under the use of a thickener to improve the physical properties of the ternary precursor.The results show that the slurry is concentrated by the thickener and then returned to the reactor for reaction.After many cycles,the particle size of the precursor increases,the particles are uniform,the morphology is regular,and the specific surface area is small.
