Supercapacitors are energy storage devices with high power density, rapid charge/discharge rate, and excellent cycle stability. Carbon-based supercapacitors are increasingly attracting attention because of their large surface area and high porosity. Carbon-based materials research has been recently centered on biomass-based materials due to the rising need to maintain a sustainable environment. Cellulose and lignin constitute the major components of lignocellulose biomass. Since they are renewable, sustainable, and readily accessible, lignin and cellulose-based supercapacitors are economically viable and environmentally friendly. This review aims to systematically analyze published research findings on electrospun lignin, cellulose, and lignin/cellulose nanofibers for use as supercapacitor electrode materials. A rigorous scientific approach was employed to screen the eligibility of relevant articles to be included in this study. The research questions and the inclusion criteria were clearly defined. The included articles were used to draw up the research framework and develop coherent taxonomy of literature. Taxonomy of research literature generated from the included articles was classified into review papers, electrospun lignin, cellulose, and lignin/cellulose nanofibers for use as supercapacitor electrode materials. Furthermore, challenges, recommendations, and research directions for future studies were equally discussed extensively. Before this study, no review on electrospun lignin/cellulose nanofiber-based supercapacitors has been reported. Thus, this systematic review will provide a reference for other researchers interested in developing biomass-based supercapacitors as an alternative to conventional supercapacitors based on petroleum products.
超级电容器是一种具有高功率密度、快速充放电速率和出色循环稳定性的储能装置。碳基超级电容器因其大表面积和高孔隙率而越来越受到关注。由于维持可持续环境的需求不断增加，基于生物质的材料近来已成为碳基材料研究的核心。纤维素和木质素是木质纤维素生物质的主要成分。由于它们可再生、可持续且易于获取，基于木质素和纤维素的超级电容器在经济上可行且环保。本综述旨在系统分析已发表的关于用作超级电容器电极材料的电纺木质素、纤维素和木质素/纤维素纳米纤维的研究结果。采用了严谨的科学方法来筛选纳入本研究的相关文章的合格性。明确界定了研究问题和纳入标准。利用纳入的文章制定研究框架并开发连贯的文献分类法。从纳入文章中生成的研究文献分类法分为综述论文、用作超级电容器电极材料的电纺木质素、纤维素和木质素/纤维素纳米纤维。此外，还广泛讨论了未来研究的挑战、建议和研究方向。在本研究之前，尚未有关于基于电纺木质素/纤维素纳米纤维的超级电容器的综述报道。因此，本系统综述将为其他有兴趣开发基于生物质的超级电容器以替代基于石油产品的传统超级电容器的研究人员提供参考。
