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.

Hierarchical porous carbon aerogels were synthesized from lique ed wood via physical and chemical activation. The morphology and structure of the KOH treated carbon aerogel (K-LWCA) and steam treated carbon (H-LWCA) were systematically investigated by SEM, N 2 adsorption, FTIR, XRD and XPS, and the electrochemical properties were evaluated based on cyclic voltammetry, galvanostatic charge-discharge and electrochemical impedance spectroscopy. The H-LWCA and K-LWCA had the high reached speci c surface area (1996 and 1780 cm 2 g − 1 , respectively) and developed hierarchical porous structures.Compared with H-LWCA, K-LWCA showed the higher speci c capacitance, better rate performance and superior cyclic stability due to more defects and hydrophilic functional groups. As expected, the K-LWCA exhibited the optimal mass-speci c capacitance of 201.47 F g − 1 at 0.5 A g − 1 , and achieved ideal capacitance retention of 70.15% at 20 A g − 1 as well as exceptional cycling stability of 94.11% retention after 5000 cycles. Moreover, the button symmetric supercapacitor device assembled based on K-LWCA demonstrated a speci c capacitance of 117.78 F g − 1 at 0.5A g − 1 and presented an energy density of 9.2 Wh kg − 1 at a power density of 375W kg − 1 . Accordingly, this work provides a novel approach for the preparation of biomass-derived carbon aerogel electrode materials in practical supercapacitor applications.
