Metal organic framework-based materials for metal-ion batteries

The next-generation energy storage systems based on metal-ion batteries are essential for implementing renewable energy sources and the high-quality development of electric vehicles. Efficient metal-ion batteries require both high energy density and high power density. However, there are challenges in the current battery systems due to poor reaction kinetics, making them difficult to fully meet these requirements. Metal-organic frameworks (MOFs), with their high porosity, multifunctionality, structural diversity, and controllable chemical composition, can serve as catalysts in electrode materials, regulate interface interactions, and improve electrochemical redox kinetics, providing new ideas and possibilities for energy storage materials. Despite these advantages, MOF-based materials are still at their early stages for their applications in the field of electrochemical energy storage and face many challenges. This article reviews the research and development of MOFbased materials in various metal-ion batteries, especially for cathodes, anodes, separators, and electrolytes due to their distinctive structure and properties. It also discusses the mechanisms for improving the electrochemical performance of metal-ion batteries. Finally, the main challenges and prospects for MOF-based materials in metalion batteries are provided.
