Abstract  Modified spinel lithium manganate with zirconium doped LiMn2-xZrxO4 (x= 0, 0.01, 0.02, 0.04, 0.06, 0.08, 0.10) used for cathode of lithium-ion batteries was prepared by solid-state method. The structure and morphology of as-prepared cathode materials were characterized by XRD and ESEM (environment scanning electron micrograph). The effects of the zirconium doping on improving the performances of spinel materials were analyzed in terms of the crystal structure, charge-discharge curves and cycle performances. The results showed that the modified materials had better cycle performances without significant degradation of capacity when the doping value x was less than 0.06,and LiMn1.98Zr0.02O4 was the best compound with a capacity of 113.8 mA•h•g-1 after 50 cycles.
