摘要

利用苯胺在稻草衍生碳(RSC)表面的原位化学聚合,合成了一种新型复合电极材料。详细的结构表征验证了颗粒状聚苯胺(PANI)在 RSC 表面的有效结合。对 RSC@PANI 电极的超级电容器性能进行了系统研究,在电流密度为 1 Ag-1 时,其比电容高达 408 Fg-1。此外,在电流密度为 10 Ag-1 时,RSC@PANI 在 1000 次循环后的电容保持率为 93%。除了出色的电化学性能外,所制备的 RSC@PANI 电极还具有可扩展性和轻质等优异特性。这项研究为 RSC@PANI 的合成和表征提供了宝贵的见解,RSC@PANI 是一种很有前途的超级电容器电极材料。

Rice Straw-Derived Carbon Integrated with PANI as an Electrode Material for High-performance Supercapacitor
A novel composite electrode material has been synthesized using in-situ chemical polymerization of aniline over the surface of rice straw-derived carbon (RSC). The detailed structural characterization validates the effective incorporation of granular polyaniline (PANI) over the RSC surface. The supercapacitor performance of the RSC@PANI electrode was systematically investigated and achieved as high as specific capacitance of 408 Fg-1 at a current density of 1 Ag-1. Moreover, RSC@PANI shows 93% capacitance retention after 1000 cycles at a current density 10 Ag-1. Apart from its outstanding electrochemical performance, the resulting RSC@PANI electrode exhibits exceptional characteristics such as scalability and lightweight properties. This study contributes valuable insights into the synthesis and characterization of RSC@PANI as a promising electrode material for supercapacitors.
