CNT‐containing redox active nanohybrid: a promising ferrocenyl‐based electrode material for outstanding energy storage application

Abstract

AbstractRedox‐active porous polymers are promising electrode materials due to various advantages including high specific surface area and porosity, facile synthesizing route, and excellent chemical and thermal stability. Herein, a simple and cost‐effective Schiff base reaction was used to prepare the ferrocene (Fc) containing porous organic polymer (POP) through the formation of a C‐N bond between melamine and 1,1′‐diacetylferrocene. After successful preparation of the Fc‐POP, Fc‐POP/PANI nanohybrid was prepared by the hybridization of synthesized redox‐active polymer with polyaniline (PANI) as a conductive polymer. Finally, the CNT (carbon nanotube)‐containing nanocomposites were prepared by adding various amounts of the CNT to Fc‐POP/PANI nanohybrid. All as‐prepared electrode materials were thoroughly characterized with usual analyses. The Fc‐POP/PANI/CNT20 revealed a high specific capacitance of 494 mAh g−1 at 2.5 A g−1 and excellent charge storage retention (92.1%) over 5000 cycles. Also, the fabricated symmetric cell exhibits a high energy density of 76 W h kg−1 and a high‐power density of 5840 W kg−1.
