- Abstract
Internally or self-doped oxygen–nitrogen–phosphorus heteroatoms are useful in increasing the hydrophilicity, wettability, and conductivity of supercapacitor cell electrodes. These properties are positively related to electrochemical supercapacitive behavior. Therefore, this study aimed to examine activated green resources from black tiger shrimp shells (BTS) to produce O-N-P self-co-doped carbon (C) nanofibers for a high-performance supercapacitor. KOH was used to determine the content of heteroatoms in the carbon matrix. The results showed that the composition of BTS contained 10.01 wt% nitrogen, 40.92 wt% carbon, 23.16 wt% oxygen, and 4.92 wt% phosphorus, confirming the presence of O-N-P self-doping. Furthermore, the carbon matrix exhibited a nanofiber structure with the presence of nanopores (micro-mesopore co-extension), which showed the highest specific capacitance of 315 F/g at 1 mV/s in 1 M H2SO4 solution. BTS supercapacitor cells designed on a symmetrical electrode system achieved a specific power of 323 W/Kg at a specific energy of 9.59 Wh/Kg. These results indicated that internal heteroatoms doping was a strategy for improving the electrochemical performance of environmentally friendly, efficient, economical, and sustainable supercapacitor cells.
