| Abstract: | Composite cathode including LiMn2O4 and modification layer of polyaniline was prepared by 'in situ' electrochemical method. The effects of scanning voltage region and monomer concentration on the performance were discussed. As a result, the composite cathode had better electrochemical performance, and excellent characteristic in high temperature. |
