摘要
随着车载锂离子动力电池对于能量密度要求的不断提高,镍钴锰三元正极材料不断向高镍含量、高电压、高压实密度和高安全性的方向发展。镍钴锰三元前驱体对三元正极材料的生产至关重要,三元前驱体的品质直接决定了三元正极材料的性能发挥。高性能镍钴锰三元前驱体是生产锂离子动力电池用三元正极材料的基础,制备高性能镍钴锰三元前驱体,合成工艺是关键。浅析了传统合成工艺与新型多釜连续合成工艺的优劣,并对合成的镍钴锰三元前驱体产品性能指标进行了对比。
With the increasing energy density requirements of on-board power lithium-ion batteries,nickel-cobalt-manganese ternary cathode materials continue to develop in the direction of high compacted density,high voltage,high nickel content and high safety.Ternary precursors are very important to the production of ternary cathode materials,and the quality of ternary precursors directly determines the physical and chemical indexes of ternary cathode materials.High performance nickel-cobalt-manganese ternary composite hydroxide precursor is the basis for the production of ternary nickel-cobalt-manganese cathode materials for power lithium-ion batteries.The synthesis process is the key to prepare high performance nickel-cobalt-manganese ternary composite hydroxide precursor.In this paper,the advantages and disadvantages of the traditional synthesis process and the new multikettle continuous synthesis process are analyzed,and the performance of the nickel cobalt manganese ternary precursor are compared.
