Supercapacitors exhibit considerable potential as energy storage devices due to their high power density, fast charging and discharging abilities, long cycle life, and eco‐friendliness. With the increasing environmental concerns associated with synthetic compounds, the use of environment friendly biopolymers to replace conventional petroleum‐based materials has been widely studied. Biomass‐based materials are biodegradable, renewable, environment friendly and non‐toxic. The unique hierarchical nanostructure, excellent mechanical properties and hydrophilicity allow them to be used to create functional conductive materials with precisely controlled structures and different properties. In this review, the latest development of biomass‐based supercapacitor materials is reviewed and discussed. This paper describes the physical and chemical properties of various biopolymers and their impact on supercapacitors, as well as the classification and basic principles of supercapacitors. Then, a comprehensive discussion is presented on the utilization of biomass‐based materials in supercapacitors and their recent applications across a range of supercapacitor devices. Finally, an overview of the future prospects and challenges pertaining to the utilization of biomass‐based materials in supercapacitors is provided.

“…The first, utilizes N-rich precursors, such as sucrose, polyacylonitrile, melamine, urea, etc., to obtain carbon structures doped with nitrogen heteroatoms. [22][23][24][25] The second, involves the treatment of carbons with nitrogen-rich reagents, including NH 3 gas, amines, nitric acid and so on. [26][27][28] However, in the case of N-doped porous carbon synthesized by the post-treatment method, functional groups are simply attached to the surface of the carbon material by adsorption.…”

A novel activated nitrogen‐doped hierarchically porous carbon (ANPC) material has been synthesized using polyurethane foam as the supporting template, phenolic resin with a high carbonization ratio, and low‐cost ammonium polyphosphate as the carbon and nitrogen sources, respectively. The preparation process comprises curing and carbonization combined with KOH activation. Despite the simplicity of the process, the obtained ANPC‐4 exhibits a high specific surface area (1452 m2 g−1), a well‐developed specific pore volume (0.799 cm3 g−1), moderate mesoporous content (32.7%), good electrolyte ions transport property, and appropriate nitrogen dopant content. When used as a material for fabricating supercapacitor electrodes, the ANPC‐4 exhibits a significantly high capacitance value of 356 F g−1 at 0.2 A g−1 in a 6 M KOH electrolyte with outstanding rate performance. In addition, the symmetrical capacitors assembled by ANPC‐4 have good specific capacitance (175 F g−1 at 0.2 A g−1), high energy density up to 24.3 Wh kg−1, and good cycling stability (94.5% capacitance retention after 10 000 cycles of testing).

“…[24][25][26][27] Among them, electrospun PAN fibers have favorable spinnability and a high carbon yield (50%), and are the most used precursors for the preparation of CNFs because of their excellent flexibility and fiber formation ability during the electrospinning and carbonization process. [28][29][30] However, considering the economics and sustainability, natural polymers and their derivatives are regarded as the best alternative to replace synthetic polymers in producing carbon materials. [31][32][33][34] Cellulose acetate, a cellulose derivative, can be made into fibers with large specific surface area, excellent porous structure and high mechanical strength.…”
