Abstract: Lithium acetate,manganese acetate,cobalt acetate,nickel acetate,citric acid,and glycol being the raw anaterials,LiMn1.8Co0.1Ni0.1O4 powder was prepared by the combustion-assisted complexing method.The phase identification,lattice parameter and morphology were studied by X-ray diffraction and scanning electron microscopy.The electrochemical properties of LiMn1.8Co0.1Ni0.1O4 were carried out by A.C.impedance and galvanostatic charge-discharge experiments.The powders prepared under different conditions are of good crystallinity;the diffraction peak of X-ray is intensive and sharp.The capacity of LiMn1.8Co0.1Ni0.1O4 increases as the temperature rises.Compared with the original capacity,it decreases slighty;however,the cycling behavior improves after double doping.

Key words: complexing method, doping, lithium ion, electrochemistry
