摘　　要：前驱体对锂离子电池正极材料Li Mn2O4结构和性能有重要影响。综述了常见的前驱体特点及生产工艺,指出二氧化锰仍然是目前用量最大的前驱体,适当的体相掺杂是改善其性能的有效途径;用球形四氧化三锰制备高性能Li Mn2O4有广阔的应用前景,改善生产工艺、降低成本必将提升球形四氧化三锰在锂离子电池领域的竞争力。The structures and properties of Li Mn2O4,which is used as cathode material for lithium ion battery,is greatly effected by its precursors.The characteristics and production technologies of common precursors for Li Mn2O4cathode were summarized.It was pointed out that Mn O2is still the most used precursor for Li Mn2O4at present and proper bulk doping is an effective way to improve its properties.Spherical Mn3O4has broad application prospect in preparation of high performance Li Mn2O4The competitiveness of spherical Mn3O4in the field of lithium ion batteries will be certainly enhanced by improving production technology as well reducing cost.
