氧化还原阴离子掺杂的聚吡咯储锂正极
摘要
We demonstrate here a great enhancement on the electrochemical utilization and high-rate capability of polypyrrole chains by doping with redox-active hexacyanocolbate, molybdate and diphenylamine sulfonate anions. The doped redox-active anions can not only contribute their redox capacity to the material, but also serve as redox mediator to accelerate the charge transfer process on the polymer chains, showing a remarkable electrochemical activation of the polymer chains. Since the doping method developed in this work is simple and is easily extended to different polymer networks, it is possible to use this new strategy for creating high capacity and low costcathode materials for advanced Li-ion batteries.
