Research progresses on metal‐organic frameworks for sodium/potassium‐ion batteries

Abstract

Metal‐organic frameworks (MOFs), as a new type of functional material, have received much attention in recent years. High ionic conductivity, large specific surface area, controllable pore structure and geometry make it possible to be used as electrode materials. Meanwhile, different types of MOF derivatives can be prepared by adjusting the metal central element, which provides options for finding electrode materials for high‐performance batteries. This paper reviews the recent research progress of pristine MOFs for sodium/potassium‐ion batteries. In addition, this paper describes the working principle, advantages, and challenges of MOFs in sodium/potassium‐ion batteries, strategies to improve the electrochemical performance, as well as future prospects and directions.
