Solid-state electrolytes (SSEs) are the key materials in the new generation of all-solid-state lithium ion/metal batteries. Metal-organic frameworks (MOFs) are ideal materials for developing solid electrolyte because of their structural diversity and porous properties. However, there are several significant issues and obstacles involved, such as lower ion conductivity, lesser ions transport number, narrower electrochemical stability window and poor interface contact. In this review, a comprehensive analysis and summary of the unique ion-conducting behavior of MOFs-based electrolytes in rechargeable batteries are presented, and the different design principles of MOFs-based SSEs are classified and emphasized. Accordingly, these MOFs-based SSEs are divided into four design principles and the changes of SSEs combined with MOFs on the electrochemical performance of the batteries are described. Finally, the challenges of MOFs materials in the lithium ion/metal batteries applications are explored, and directions for future research of MOFs-based electrolytes are proposed. This review will deepen the understanding of MOFs-based electrolytes and promote the development of high-performance solid-state lithium ion/metal batteries. This review not only provides theoretical guidance for the research of new MOFs-based SSEs systems, but also contributes to the further development of MOFs applied to rechargeable batteries.
