摘要
与商业化电池相比,水系有机电池(AOBs)具有低成本、高安全性、环保等特点,使其更适用于便携电子设备和电网储能应用。电极材料作为水系有机电池重要组成部分,在实现电池的高容量和长循环寿命方面起到至关重要的作用。基于绿色发展的需求,有机电极材料应具备理论比容量高、资源丰富、设计灵活性强等优点。本文综述了不同储能机理的有机电极材料的最新研究进展,包括羰基化合物、亚胺化合物、导电聚合物、COFs材料、MOFs材料以及复合材料等。同时总结了有机电极材料在水系电池中的导电性和溶解性问题,并提出了不同的解决策略。最后,讨论了水系有机电池的关键挑战以及未来努力方向,未来仍需要更多具有更好电子导电性和快速动力学的电极材料应用于水系有机电池。
Compared with present commercial batteries,aqueous organic batteries(AOBs),with improved safety,environmental benignity,and affordability,are very appealing for portable electronics and gridscale applications.The electrode material is an important component of AOBs,which plays a critical role in achieving high energy and long cycle life of aqueous batteries.In the context of green development,organic electrode materials show advantages of environment friendliness,resource renewability and design flexibility.This paper reviewed the latest research progress of organic electrode materials with different storage mechanisms,including conducting polymers,carbonyl compounds,imine compounds,COFs/MOFs materials and compound materials,and summarizd their conductivity and dissolution issues.At the same time,their conductivity and dissolution issues,and strategies to enhance the electrochemical performance of organic electrode materials were also introduced.Finally,the critical challenges and future efforts of aqueous organic batteries were discussed.More organic electrode materials with better electronic conductivity and fast reaction kinetics were still needed to build AOBs.
