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

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. Metal-organic frameworks (MOFs) have been widely used in energy storage due to their unique structures and properties. This review systematically summarizes the recent progress of MOFs in sodium-ion and potassium-ion batteries and analyzes the problems of MOFs in batteries, providing guidance for the development of high-performance materials for MOFs. image
