With the swift advancement of the wearable electronic devices industry, the energy storage components of these devices must possess the capability to maintain stable mechanical and chemical properties after undergoing multiple bending or tensile deformations. This circumstance has expedited research efforts toward novel electrode materials for flexible energy storage devices. Nonetheless, among the numerous materials investigated to date, the incorporation of metal current collectors or insulative adhesives remains requisite, which entails additional costs, unnecessary weight, and high contact resistance. At present, biomass-derived flexible architectures stand out as a promising choice in electrochemical energy device applications. Flexible self-supporting properties impart a heightened mechanical performance, obviating the need for additional binders and lowering the contact resistance. Renewable, earth-abundant biomass endows these materials with cost-effectiveness, diversity, and modulable chemical properties. To fully exploit the application potential in biomass-derived flexible carbon architectures, understanding the latest advancements and the comprehensive foundation behind their synthesis assumes significance. This review delves into the comprehensive analysis of biomass feedstocks and methods employed in the synthesis of flexible self-supporting carbon electrodes. Subsequently, the advancements in their application in energy storage devices are elucidated. Finally, an outlook on the potential of flexible carbon architectures and the challenges they face is provided.
随着可穿戴电子设备行业的迅速发展，这些设备的储能组件必须具备在经历多次弯曲或拉伸变形后仍能保持稳定的机械和化学性能的能力。这种情况加速了对用于柔性储能设备的新型电极材料的研究工作。然而，在迄今为止研究的众多材料中，金属集流体或绝缘粘合剂的加入仍然是必要的，这带来了额外的成本、不必要的重量和高接触电阻。目前，生物质衍生的柔性结构在电化学能量装置应用中脱颖而出，成为一种有前途的选择。柔性自支撑特性赋予了更高的机械性能，无需额外的粘合剂并降低了接触电阻。可再生、储量丰富的生物质使这些材料具有成本效益、多样性和可调节的化学性质。为了充分挖掘生物质衍生的柔性碳结构的应用潜力，了解其合成背后的最新进展和全面基础具有重要意义。本综述深入探讨了生物质原料以及用于合成柔性自支撑碳电极的方法的综合分析。随后，阐述了它们在储能设备中的应用进展。最后，对柔性碳结构的潜力及其面临的挑战进行了展望。
