N2 - Transition metals substitution in cathode materials is considered as an effective approach to improve the electrochemical performances of lithium–ion batteries. In this regard, host and Ni-substituted LiMn1-xNixPO4 (x = 0.00–0.05) olivine cathode materials were successfully synthesized by a modified solution combustion method. The structural and morphological properties were examined by X–ray diffraction (XRD), Field emission scanning electron microscopy (FE-SEM), Transmission electron microscopy (TEM) and Raman spectroscopy. According to X-ray diffraction results, all substituted materials LiMn1-xNixPO4/C adopt an identical structure to that of the LiMnPO4 olivine structure, suggesting that the nickel ion has been well incorporated into the crystal lattice, without any changes in the host material structure. When x = 0.05, the material shows an excellent specific capacity and stability during charge …
