Application of Metal-Organic Frameworks for Battery Separators

With the rapid development of the new energy industry, research on different kinds of high-performance batteries has become a hot topic nowadays. As one of the important components of batteries, the separator can effectively prevent direct contact between positive and negative electrodes of batteries and provide favorable channels for ion transport. However, traditional polymer battery separators usually have problems such as insufficient thermal stability, poor ion transport capacity, and poor electrolyte wettability. As a new type of porous crystalline material, metal-organic frameworks (MOFs) have become the current research hotspot for high-performance battery separators due to their high porosity, high specific surface area and excellent thermal stability. In this paper, the applications of various MOFs or MOFs-based materials in battery separators are reviewed, and the advantages and disadvantages of MOFs-based battery separators are comprehensively discussed. Finally, the urgent problems to be solved in the field of MOFs-based battery separators and the development prospects of MOFs in battery separators are presented.
