Ionic conductors (ICs) find widespread applications across different fields, such as smart electronic, ionotronic, sensor, biomedical, and energy harvesting/storage devices, and largely determine the function and performance of these devices. In the pursuit of developing ICs required for better performing and sustainable devices, cellulose appears as an attractive and promising building block due to its high abundance, renewability, striking mechanical strength, and other functional features. In this review, we provide a comprehensive summary regarding ICs fabricated from cellulose and cellulose-derived materials in terms of fundamental structural features of cellulose, the materials design and fabrication techniques for engineering, main properties and characterization, and diverse applications. Next, the potential of cellulose-based ICs to relieve the increasing concern about electronic waste within the frame of circularity and environmental sustainability and the future directions to be explored for advancing this field are discussed. Overall, we hope this review can provide a comprehensive summary and unique perspectives on the design and application of advanced cellulose-based ICs and thereby encourage the utilization of cellulosic materials toward sustainable devices.
离子导体（ICs）在不同领域有着广泛应用，如智能电子、离子电子、传感器、生物医学以及能量收集/存储设备等，并且在很大程度上决定了这些设备的功能和性能。在致力于开发性能更优且可持续的设备所需的离子导体过程中，纤维素因其丰富的储量、可再生性、显著的机械强度以及其他功能特性，成为一种颇具吸引力且前景广阔的基础材料。在这篇综述中，我们从纤维素的基本结构特征、用于工程设计的材料设计与制备技术、主要性能及表征以及多样的应用等方面，对由纤维素及其衍生材料制备的离子导体进行了全面总结。接下来，讨论了基于纤维素的离子导体在循环利用和环境可持续性框架内缓解对电子垃圾日益增长的担忧的潜力，以及为推动该领域发展有待探索的未来方向。总体而言，我们希望这篇综述能够对先进的基于纤维素的离子导体的设计与应用提供全面总结和独特见解，从而促进纤维素材料在可持续设备中的利用。
