摘要
采用碳酸钠和碳酸氢铵作为沉淀剂和络合剂,在水溶液中共沉淀Mn2+、Ni2+和Co2+以获得混合过渡金属元素的碳酸盐沉淀前驱体Mn0.675Ni0.1625Co0.1625CO3。并进一步合成高容量锂离子电池正极材料Li[Li0.2Co0.13Ni0.13Mn0.54]O2。考察了3种不同加料方式对共沉淀前驱体的结构、形貌和元素比例的影响,以及对最终产物的结构、形貌和电化学性能的影响。
The precursor of Mn0.675Ni0.1625Co0.1625CO3 has been synthesized by a carbonate co-precipitation method, which was used to prepare a high capacity cathode material Li Li[Li0.2C00.13N0.13Mn0.54]O2 for lithium ion batteries. Three kinds of raw materials feeding ways during co-precipitation process were compared. The chemical and physical properties of the precursor and LiLi[Li0.2C00.13N0.13Mn0.54]O2 have been systematically studied.
