| 摘 要： | 通过正交实验法,采用流变相法制备了LixCoyNizMn2-y-zO4的25个样品(x=1、1.02、1.04、1.06、1.08,y=0、0.025、0.05、0.075、0.1,z=0、0.025、0.05、0.075、0.1),并对其电化学性能进行了研究从而选择出最佳原料配比。实验结果表明从首次放电比容量来考察LiCo0.05Mn1.95O4的性能最好,从第20次容量保持率来考察Li1.06Co0.1Ni0.075Mn1.825O4的性能最好。

| Abstract: | Twenty five different samples like LixCoyNizMn2-y-zO4(as x is 1,1.02,1.04,1.06 or 1.08,y is 0,0.025,0.05,0.075 or 0.1 and z is 0,0.025,0.05,0.075 or 0.1)were synthesized by the rheological phase reaction method.The electrochemical properties of these samples were also investigated.The results showed that LiCo0.05Mn1.95O4 had the best initial discharge capacity and Li1.06Co0.1Ni0.075Mn1.825O4 had the best cycle stability. |
