- W2275193045 abstract "采用低温共沉淀-水热-煅烧法合成了锂离子电池Fe-Ni-Mn体系正极材料Li1-x(Fey/2Niy/2Mn1-y)1-xO2,并用XRD、SEM、ICP光谱和电化学性能测试对材料进行了表征。XRD测试和ICP分析表明,Fe、Ni取代Li2Mn03中的部分Mn,形成很好的固溶结构yLi1-x(Fey/2Niy/2Mn1-y)1-xO2(y=0.1,0.2,0.3,0.4,0.5)。SEM测试表明,取代量Y不同,材料的表观形貌有所不同,y=0.4时材料的颗粒粒径均匀、较小,呈类球形结构。电化学性能测试表明,当y=0.4时,循环稳定性最好,充放电50次后放电比容量仍可维持在195.0mAh/g,放电中值电压为3.5V,y=0.4时样品在大倍率放电下的电化学性能表现良好。" @default.
