摘　　要：采用高温烧结前驱体共沉淀法合成Li1+xNi1/3Co1/3Mn1/3O2,着重研究了烧结温度对合成产物性能的影响,研究结果表明:于900℃合成产物性能优良,放电容量为162.2mAh/g,充/放电效率为91.3%,20次循环后容量保持率为96.4%,显示出良好的循环特性。Li1＋xNi1/3Mn1/3O2 were synthesized by high temperature sintering precursor co-precipitation method, and the effect of sintering temperature on material performance was discussed. The results show that the material prepared at 900℃ has better electrochemical character, and its discharge capacity is 162.2 mAh/g, the charge-discharge efficiency is 91.3%, the capacity retaining is 96.4% after 20 cycles. And the material showed a high cyclic performance.
