Abstract

Capacitive deionization (CDI) is a promising technology for addressing global freshwater scarcity, and bacterial cellulose (BC), with its unique 3D nanostructure and sustainable nature, has emerged as an ideal material for CDI and faradic CDI (FDI) applications by enhancing desalination efficiency with minimal cost and manufacturing pollution. Despite these advantages, a comprehensive understanding of how BC's structural characteristics influence CDI and FDI performance is still lacking. This review, therefore, systematically evaluates recent advances in BC-derived materials for CDI, focusing on i) BC-derived carbon for electric double layer (EDL)-based CDI and FDI, ii) how its key properties (e.g., high conductivity, 3D networks, freestanding nature) address critical challenges (e.g., charge/mass transfer) of CDI/FDI, and iii) its potential to enable innovative cell designs like flow-through architectures. This review aims to provide fundamental principles and guidelines for optimizing BC-based CDI electrodes, paving the way for future innovations in BC-based CDI.

细菌纤维素：一种多功能3D纳米结构，推进了高性能电容去离子的电极工程

电容性去离子（CDI）是解决全球淡水短缺问题的一种很有前途的技术，而细菌纤维素（BC）由于其独特的3D纳米结构和可持续性，已成为CDI和faradic CDI （FDI）应用的理想材料，可以以最低的成本提高海水淡化效率，并减少污染。尽管有这些优势，但对BC的结构特征如何影响CDI和FDI绩效的全面理解仍然缺乏。因此，本综述系统地评估了用于CDI的bc衍生材料的最新进展，重点关注i)用于双层电（EDL） CDI和FDI的bc衍生碳，ii)其关键特性（例如，高导电性，3D网络，独立性）如何解决CDI/FDI的关键挑战（例如，电荷/传质），以及iii)其实现创新电池设计的潜力，如流动结构。本综述旨在为优化bc基CDI电极提供基本原则和指导，为未来bc基CDI的创新铺平道路。
