Recent progress on construction and applications of metal-organic frameworks-based materials for lithium-ion batteries and supercapacitors

Metal-organic frameworks (MOFs), a special sort of three-dimensional crystalline porous lattices composed of organic multi-site connectors and metal nodes, are characterized by unique porosity and high specific surface area, which have attracted a wide range of interest as electrode materials for the electrochemical energy storage devices in recent years. In this contribution, we outline the current research progress on the construction of pristine MOFs, MOF composites, and MOF derivatives and their applications as electrode materials in supercapacitors (SCs) and lithium-ion batteries (LIBs). Specifically, we discuss the shortcomings of MOFs-based electrode materials for SCs and LIBs. The innovative work on performance improvements by combining MOFs with other conductive materials and derivating MOFs into metal sulfides, metal oxides, metal phosphides, and porous carbon is also presented in detail. Finally, our perspectives on the challenges in the future for a grasp of the potential mechanisms are tentatively provided. This review will inspire more developments and applications of MOFs-based electrode materials for electrochemical energy storage. This work provides an overview of current approaches for the construction of pristine metal-organic frameworks (MOFs), MOF composites and MOF derivatives, and also describes research on the applications of MOF-based materials as electrode materials for lithium-ion batteries and supercapacitors. On this basis, some future challenges are tentatively provided in grasping the underlying mechanisms. image
