【摘要】：导电聚苯胺(PANI)是近十年来研究最多的导电聚合物,具有比容量高、氧化还原可逆性好、电导率高、合成方法简单、成本低等特点,在化学电源和超级电容器中的应用最为广泛。导电聚苯胺复合材料的合成方法主要分为:原位复合法、共混法、自组装和电化学复合法等。导电聚苯胺复合材料可作为高能物质用于研发电极材料,但目前利用导电聚苯胺对锂离子电池三元正极材料进行修饰改性的研究较少。综述了导电聚苯胺及其复合材料的热电化学性能,重点对导电聚苯胺/锂离子电池复合正极材料的性能进行了阐述。最后对导电聚苯胺复合材料的应用和研究方向进行了总结,并简述了导电聚苯胺包覆改性LiNi_(1-x-y)Co_xMn_yO_2复合材料的应用和展望。
[Abstract]:Conductive Polyaniline (pani) is the most studied conducting polymer in recent ten years. It has the characteristics of high specific capacity, good redox reversibility, high conductivity, simple synthesis method and low cost. It is widely used in chemical power supply and supercapacitor.The synthesis methods of conductive Polyaniline composites are as follows: in situ compounding, blending, self-assembly and electrochemical recombination.Conductive Polyaniline composites can be used as high energy materials to develop electrode materials, but there is little research on modification of lithium ion battery ternary cathode materials by conducting Polyaniline.The thermoelectric and chemical properties of conductive Polyaniline and its composites are reviewed, and the properties of conductive Polyaniline / lithium ion battery composite cathode materials are emphatically described.Finally, the application and research direction of conductive Polyaniline composites are summarized, and the applications and prospects of conductive Polyaniline coated modified LiNi_(1-x-y)Co_xMn_yO_2 composites are briefly described.
