摘要： LiMn2O4 nanoparticles were prepared in this study by solid state reaction using nano-sized MnO2 as precursor. MnO2 nanoparticles were prepared via hydrothermal technique and were used as precursors for preparation of the LiMn2O4 nanoparticles. The size of the synthesized LiMn2O4 nanoparticles was about 600.800 nm. The as-synthesized LiMn2O4 nanoparticles exhibited good electrochemical performance with an initial discharge capacity of 135.5 mAh.g(-1) at current density of 29.6 mA.g(-1). The LiMn2O4 nanoparticles showed wonderful cycle ability and capacity retention ratio was 95.94% after 100 cycles at the current density of 296 mA.g(-1).
