Abstract

Polyaniline can be used as a high capacity cathode material due to the advantages of material abundance and synthetic simplicity. However, its practical application in battery has been hindered by poor electrochemical utilization and cycling instability. To solve these problems, we synthesized the poly(aniline/o-Nitroaniline) (P(AN-oNA)) by introducing the electron-drawing group-nitroaniline onto the polyaniline chains, so as to enhance electrochemical utilization and stability of the polyaniline derivative. The as-prepared Li/P(AN-oNA) copolymer shows a greatly enhanced discharge capacities of 186 mAh.g^-1 at initial cycles, about 37% higher than its parent PAN, and remains 168 mAh.g^-1 after 60th cycle. Also, the Li/P(AN-oNA) copolymer exhibits very similar charge and discharge profiles, demonstrating a significantly decreased polarization. This structural modification of PAN and the resulting improved performances of the Li/P(AN-oNA) copolymer suggest an effective way to develop high capacity organic cathode materials for Li-ion batteries.
