Olivine structure LiMnPO/C as cathode materials for Li-ion batteries were synthesized via a simple solid-state reaction. Improvement of the electrochemical performance of LiMnPO_4/C cathode material was realized significantly by the method of doping Zn. The obtained LiMn_0.95Zn_0.05PC_4/C electrode material was studied by the measurements of X-ray diffraction pattern, scanning electronic microscopy, electrochemical impedance spectroscopy and electrochemical performance. The results indicate that the LiMn_0.95Zn_0.05PC_4/C materials exhibit discharge specific capacity of 140.2 mA h g~-1 at 0.02...
