Effect of Nickle Substitution on the Performance of Lithium Ion Battery Material LiMnTiO$lt;inf$gt;4$lt;/inf$gt;

Spinel LiMn1-xNixTiO4(x=0, 0.1, 0.2, 0.3) cathode materials were prepared by Sol-Gel method. The surface morphology and phase structure of LiMn1-xNixTiO4 (x=0, 0.1, 0.2, 0.3) were characterized by FESEM and XRD. FESEM analysis indicated all the samples consisted of irregular particles and XRD patterns showed that all the materi- als had impurity TiO2, but there were no impurities related to Ni element. Electrochemical studies of doped and un- doped spinels were carried out by cyclic voltammetry (CV) and constant current charge-discharge. CV results showed that LiMnTiO4 had two couples of sharp redox peaks corresponding to Mn
