“…Simultaneously, benefiting from the in-depth exploration of activation methods, different activators, such as KOH, Air, ZnCl 2 , H 3 PO 4 , and NaOH, have been rationally selected to activate BDC, and can effectively increase the specific surface area of BDC. [180][181][182] Moreover, according to the structure of BDC, some appropriate synthetic methods have been developed to prepare high-performance electrode materials, such as chemical vapor deposition, [283] hydrothermal, [119] self-assembly, [118] and simple impregnation process. [231] As a result, many batteries with high stability and high storage capacity have been developed.…”

“…The physical chemical coupling activation method is a twostep activation method combining the chemical activation method and physical activation method. [180,181] A chemical activator is used to impregnate the raw materials to increase the activity, which can form a channel for transporting activated gas inside, [182] and then pass the gas at a high temperature for physical activation. [182] The pore structure of activated carbon prepared by this method can be effectively controlled.…”

Owing to the sustainability, environmental friendliness, and structural diversity of biomass-derived materials, extensive efforts have been devoted to use them as energy storage materials in high-energy rechargeable batteries. A timely and comprehensive review from the structures to mechanisms will significantly widen this research field. Here, it starts with the operation mechanism of batteries, and it aims to summarize the latest advances for biomass-derived carbon to achieve high-energy battery materials, including activation carbon methods and the structural classification of biomass-derived carbon materials from zero dimension, one dimension, two dimension, and three dimension. Each strategy starts with carefully selected examples and then moves to illustrate the underlying transport mechanism of electrons in the structure. In the end, challenges, strategies, and outlooks are pointed out for the future development of biomass-derived carbon materials. Overall, this review will help researchers choose appropriate strategies to design biomass-derived carbon materials, thereby promoting the application of biomass materials in battery design.

In the past decades, fossil energy depletion, environmental pollution, and greenhouse gas emissions have resulted in serious health threats and ecological imbalances, which prompt researchers to explore green and sustainable supercapacitor energy storage and conversion systems. Biomass is a promising renewable energy source to use for biomass porous carbon for supercapacitor devices because it is renewable and has abundant reserves, a low price, and low pollution carbon energy. To date, although some reports have screened different biomass precursors, carbonization methods, and activation strategies and mechanisms, a comprehensive evaluation and critical review of the correlation among biomass porous carbon properties, including pore structure and surface chemistry, and electrochemical energy storage performances of supercapacitors are absent from a multidisciplinary assessment perspective. Therefore, in this review, we summarize recent advances in the biomass porous carbon synthesis process focusing on different carbonization and activation strategies, point out the scope of applicability and advantages/disadvantages of these methods in supercapacitor applications, and reveal the reaction mechanisms and limitations for commercial production. Then, the relationships among biomass porous carbon properties, including hierarchical porous structure, surface chemistry, specific surface area, and electrochemical performances of supercapacitors are reviewed in detail, which enables researchers to prepare and design advanced materials in a more rational way and facilitates them to explore more cutting-edge energy storage materials. Finally, two effective techniques including heteroatom doping and composite material construction are reviewed to address the general problem of low supercapacitor energy density. This review demonstrates the great potential of biomass porous carbon with superior properties, provides advanced tailoring and design viewpoints for the application fields of high-performance supercapacitors, and is expected to inspire new exploration and boost the practical commercial applications of biomass-derived hierarchical porous carbon material in more energy storage and conversion fields.
