The pods were carbonized at temperatures ranging from 400 C to 1000 C, with CNS at 800 C (MC800) showing best electrochemical performance. The synthesized materials, i.e., MC400, MC600, MC800, MC1000, were characterized by techniques such as FESEM, HR-TEM, FTIR, XRD, Raman spectroscopy, and BET. Amide functionalization, achieved through the use of 2,3,4-trifluoroaniline (TFA), enhanced charge storage capacity by improving ion transport and surface interaction, resulting in the functionalized CNS labeled as MC800/COOH-TFA. The electrochemical investigation of the CNS was studied via techniques such as cyclic voltammetry (CV), galvanostatic charge-discharge (GCD) and electrochemical impedance spectroscopy (EIS). The functionalization led to two-fold increase in specific capacitance from 243 Fg?1 to 410 Fg?1 at a current density of 0.25Ag?1 in 3 M KOH. The SSSCs was fabricated using MC800/COOH-TFA with a PVA-KOH gel electrolyte demonstrating a good areal capacitance of 40 mFcm?2 at 1.0 mAcm?2. Moreover, the device exhibited excellent energy density of 5.54 ?Whcm?2 and cycle stability, retaining 71.75 % of its capacitance after 10,000 charge-discharge cycles. The response time of the functionalized sample has been reduced to 2.31 s (MC800/COOH-TFA) from 4.73 s (MC800). These results highlight the potential of amide functionalized CNS in producing efficient, sustainable energy storage devices with improved performance. 2025 Elsevier Ltd Subject The topic of the resource Areal capacitance; Biomass; Energy density; Power density; Solid-state supercapacitor Publisher An entity responsible for making the resource available Elsevier Ltd Relation A related resource ISSN: 2352152X; Language A language of the resource English Type The nature or genre of the resource Article Rights Information about rights held in and over the resource Restricted Access; Hardcopy may be available in the library Format The file format, physical medium, or dimensions of the resource online
