Abstract: Using water soluble organic compound as matrix, Carbon-coated LiMn₂O₄ was synthesized successfully. Co-doped LiMn₂O₄ was also synthesized. Physical and electrochemical performances were investigated by XRD, IR, SEM and electrochemical testing. The results showed that due to a better conductivity and stabilization of Co-doped LiMn₂O₄, the electrochemical performances of LiMn₂O₄ were improved. And Carbon-coated LiMn₂O₄ also showed a good property because of the reduction of Mn dissolution. Comparatively speaking, Carbon-coated LiMn₂O₄ showed a more stable electrochemical performance.

Keywords: Li-ion battery LiMn₂O₄ doping surface modification
