To elevate LiMn2O4 capacity on the basis of good cyclability,the synthesis and electrochemical performance of Ni-Co co-doped LiMn2O4 were researched.All the samples synthesized by the sol-gel method possess the structure of the pure cubic spinet phase and the crystallization is superior.The electrochemical performance of LiMn1.9Co0.05Ni0.05O4 is satisfying too.In voltage range of 3.0-4.3V,the initial capacity amounts to 139 mAh/g and capacity retention reach 96.4% after 36 cycles.
