Abstract: The spinel Li intercalation compound Li 1+ x Mn 2- x O 4(0< x <1) was prepared by using techniques of cyclic voltammetry. The electrochemical parameters of Li 1+ x Mn 2- x O 4 electrode vary as either the starting materials or the synthesis temperature changes. It was found that the initial capacity and reversible behaviors of the Li 1+ x Mn 2- x O 4 electrode depends on the amount of the excess Li, represented as x in Li 1+ x Mn 2- x O 4. The reversible of Li intercalation process for Li 1+ x Mn 2- x O 4 electrode was demonstrate by cyclic voltammograms.
