The Ti-doped LiMn2O4 (LiMn1.97Ti0.03O4) nanorods are prepared by self-sacrificial template methodwith titanium dioxide (TiO2) nanoparticles and manganese hydroxide (γ-MnOOH) nanorods as dopingagent and manganese precursor, respectively. The obtained LiMn1.97Ti0.03O4 nanorods possess obviousnanorod structure and no other impurity peaks can be observed in the XRD pattern of the titanium dopedsample, which suggests the successful inheritance of nanorod structure of γ-MnOOH in theLiMn1.97Ti0.03O4 sample with high purity. According to the electrochemical results, the LiMn1.97Ti0.03O4nanorods present excellent cycling performance. When tested at 0.5 C, the LiMn1.97Ti0.03O4 nanorodsshow an initial discharge capacity of 125.1 mAh g-1 with high capacity retention of 93.8% after 100cycles. Moreover, the LiMn1.97Ti0.03O4 nanorods show better rate performance and cycling stabilityunder high temperature. This work indicates that the co-modification of Ti-doping and nanorodmorphology has synergistic effect, which can effectively help enhance the electrochemical properties ofLiMn2O4..
