摘要：

An aniline/o-nitroaniline copolymer was prepared simply by grafting electron-withdrawing o-nitroaniline groups onto polyaniline chains through a chemical oxidative polymerization and tested as a high voltage cathode material for Na-ion batteries. The experimental results demonstrated that the as-prepared P(AN-NA) can deliver a reversible capacity of 180 mAh g(-1) at an average potential of similar to 3.2 V (vs. Na+/Na) and remain 173 mAh g(-1) after 50 cycles, showing a high potential capability and a strong capacity retention. In addition, the copolymer is low cost and easy to make, possibly serving as a cycling-stable and high capacity cathode for practical Na-ion battery applications. (C) 2012 Elsevier B.V.
