Description
Summary:Recently, to ameliorate the forthcoming energy crisis, sustainable energy conversion and storage devices have been extensively investigated. Potassium-ion batteries (KIBs) have aroused widespread attention in these very active research applications due to their earth abundance and similar low redox potential compared to Li-ion batteries (LIBs). It is critical to develop electrode materials with large ion diffusion channels and robust structures for long cycling performance in KIBs. Metal coordination materials, including metal–organic frameworks, Prussian blue, and Prussian blue analogue, as well as their composites and derivatives, are known as promising materials for high-performance KIBs due to their open frameworks, large interstitial voids, functionality and tailorability. In this review, we give an overview of the recent advances on the application of metal coordination materials in KIBs. In addition, the methods to enhance their K-ion storage properties are summarized and discussed, such as morphology engineering, doping, as well as compositing with other materials. Ultimately, some prospects for future research of metal coordination materials for KIBs are also proposed. Graphic abstract
