先采用多层基底沉淀法合成镍钴锰酸锂前驱体，然后与碳酸锂混合，最后经高温煅烧，可获得中粒径达8．68μm的镍钴锰酸锂．随着基底间距增大，镍钴锰酸锂粒径增大．当基底间距为0．5cm时，可获得分布均匀、尺寸相近、形貌一致性高的镍钴锰酸锂．将镍钴锰酸锂样品作为正极材料，组装成纽扣模拟电池测其电性能，结果表明：随着镍钴锰酸锂粒径的减小，其寿命降低，但是比容量增大，最高可达151mAh/g．

Nickel cobalt lithium manganate with particle size about 8 .68μm was synthesized by multilayer substrate precipitation method using the precursor being calcined with lithium carbonate at high temperate . As the distance between substrate increased ,the partiles size of nickel cobalt lithium manganate rose . When the distance was about 0 .5cm ,the morphology of nickel cobalt lithium manganate are uniform with similar size .A simulation battery was assembled using nickel cobalt lithium manganate as anode material and the electrochemical analysis showed that cycling stability became worse as the particles of nickel cobalt lithium manganate decreased ,but discharge capability increased and it could reach 151 mAh/g .
