“…Lately, biomass-derived CNS materials [9][10][11] attract great attention of researchers because biomass is abundant, easy-to-access and sustainable. Our earlier paper [12] reported a porous CNS with a high SSA of 1234 m 2 g -1 obtained by a simple carbonisation procedure with carefully selected carbon precursors. When these porous CNS were used as electrodes in SCs, a capacitance of 213 F g -1 can be acquired at a current density of 0.1 A g -1 .…”

“…These meltable inorganic salts may play a crucial activation role and improve the specific surface area of the CFSPC material. 58 Figure 3g indicates AFM topographical observations of CFSPC, further confirming the rough and uneven surface of the sheetlike carbon. The irregular sheetlike arrangement of carbon was formed with a thickness of about 2−3 nm.…”

Herein, we report the synthesis of porous carbon material derived from the renewable source of Cassia fistula flower petals by a single-step direct-carbonization process. The sheetlike porous carbon (CFSPC) derived from C. fistula flower petals displays an uneven sheetlike morphology, hierarchical porous structure, and a high specific surface area of 556 m2 g–1. It exhibits a high specific capacitance of 324 F g–1 at the current density of 1 A g–1 and long cyclic stability of 95.3% with nearly 100% Coulombic efficiency over around 10 000 charge–discharge cycles in a two-electrode configuration. CFSPC also delivers a maximum specific energy of over 48.2 Wh kg–1 and a specific power of 687 W kg–1. These electrochemical performance results demonstrate that the as-synthesized sheetlike porous carbon derived from readily available greener resources like C. fistula flower petals may serve as promising electrodes for energy storage.

“…This indicates that NCC materials have a large number of micro- and mesoporous structures [ 23 ], which have a strong interaction with nitrogen. Meanwhile, its desorption curve overlaps with the adsorption curve without a hysteresis loop, highlighting the dominance of the microporous structure [ 24 ]. The pore size distribution was determined from their adsorption curves, and as shown, the pore size distribution peaks of the NCC samples ranged from 0 to 10 nm, confirming the microporous nature of the NCC material, which is consistent with the corresponding N 2 adsorption and desorption curves.…”

The performance of lead-acid batteries could be significantly increased by incorporating carbon materials into the negative electrodes. In this study, a modified carbon material developed via a simple high-temperature calcination method was employed as a negative electrode additive, and we have named it as follows: N-doped chitosan-derived carbon (NCC). The performance of this material was compared with a control battery containing activated carbon (AC). X-ray diffraction (XRD), scanning electron microscopy (SEM) and Raman spectroscopy were engaged in analyzing the crystal structure and morphology of the material. Afterwards, the electrochemical and battery performance was examined through cyclic voltammetry (CV), linear voltammetry (LSV) and constant current charge-discharge testing. Markedly, the electrode plate containing 1 wt.% NCC indicates the highest specific capacity (106.48 F g−1) as compared to the control battery, which is 1.56 times higher than the AC electrode plate and 4.75 times higher than the blank electrode plate. The linear voltammetry shows that the hydrogen precipitation current density of the 1 wt.% NCC electrode plate is only −0.028 A cm−2, a much higher value than that of the AC electrode plate. In addition, the simulated battery containing 1 wt.% NCC has a cycle life of 4324 cycles, which is 2.36 times longer than that of the same amount of additive AC battery (1834 cycles) and 5.34 times longer than that of the blank battery (809 cycles). In summary, NCC carbon has the advantage of extending the life of lead-acid batteries, rendering it a promising candidate for lead-acid battery additives.
