“…In addition, excellent electrochemical specific capacitance (240 F g −1 , 0.2 A g −1 ) and fine cycling stability (5000 cycles, 92%) were shown in 6 M KOH. With another study, Ma et al [ 78 ] used polymeric (PVDF‐HFP) surfactants as templates to synthesize porous carbon materials with even distribution. Due to the porous structure and N doping, the materials showed superior specific capacitance (312.2 F g −1 , 0.5 A g −1 ) and doubling performance (217.6 F g −1 , 20 A g −1 ), as well as notable specific energy and power (7.1 Wh kg −1 , 250 W kg −1 ).…”

As the core component of supercapacitors (SCs), the electrode material plays a decisive role in performance. Among electrode materials, carbon materials are the most widely used due to high porosity and specific surface area (SSA, 1000–3000 m2 g−1). Biomass carbon stands out in carbon materials because of its wide source, low cost, and less pollution. This work reviews the recent advances on carbon materials derived from biomass waste for SCs and explores the effects of different biomass sources including plant, animal, and aquatic organism waste on the performance of biomass waste‐derived carbon materials (BWDCs). Because of its high conductivity (1.25 × 103 ≈ 3 × 105 S m−1), power density (>10 kW kg−1), and extended cycle life (>10 000 cycles), BWDCs are advancing quickly in energy storage. It also discusses different methods and optimization pathways of BWDCs thoroughly. Finally, the challenges and future prospects for BWDCs are summarized. Overall, this critical will help researchers to gain a better understanding of source selection, structural classification, and research strategies for BWDCs, thereby promoting the application of BWDCs in electrochemistry and resource utilization.

“…In the three-electrode setup, the capacitances were obtained from the discharge portion of the GCD curves based on the following equation: [46] C ¼ IDt mDV (1) where C (F g À 1 ), m (g), and I (A) represent the specific capacitance of the active materials, the total mass of active materials within the working electrode, and the constant current, respectively. ΔV (V) is the voltage window during discharge with IR drop correction, and Δt (s) refers to the discharge time.…”

As a waste of the pulp and papermaking industry, industrial alkali lignin (IAL) was employed to prepare nitrogen-doped porous carbon by pre-carbonizing of lignin under a N 2 atmosphere at 400 °C and carbonizing with the assistance of urea at 800 °C for 1 h. The porosity and surface chemical properties of the obtained porous carbons strongly depended on the alkaline environment of the lignin. The obtained porous carbons showed specific surface areas ranging from 1.759 m 2 g À 1 to 1482 m 2 g À 1 and nitrogen contents of 1.12 % to 7.78 %. The unique microstructure and nitrogen functionalities endowed the porous carbon with a high capacitance of 283.4 F g À 1 in 6 mol L À 1 KOH aqueous electrolytes. In addition, the optimal porous carbon exhibited excellent rate capability (212.0 F g À 1 at 20 A g À 1 ) and cycle durability (97.6 % after 10000 charge-discharge cycles), making it a promising electrode material for supercapacitors.
