Study on the Influence of Ni0.6Co0.2Mn0.2(OH)2 Synthesis Conditions on Particle Size

Abstract

利用硫酸镍、硫酸钴、硫酸锰、氨碱、氨水为原料，采用共沉淀法制备镍钴锰三元锂电池前驱体。分析了合成过程中氨水浓度、pH、温度、陈化时长、陈化后洗水量等因素对Ni0.6Co0.2Mn0.2(OH)2粒径、形貌等指标的影响，最终选出较优的工艺条件。 Using nickel sulfate, cobalt sulfate, manganese sulfate, ammonia base and ammonia water as raw materials, the precursor of nickel cobalt manganese ternary lithium battery was prepared by coprecipitation method. The influences of ammonia concentration, pH, temperature, aging time, and washing water amount on Ni0.6Co0.2Mn0.2(OH)2 particle size and morphology were analyzed in the synthesis process, and the optimal process conditions were finally selected.
