Metal-organic frameworks (MOFs) and their derivative as electrode materials for lithium-ion batteries

Abstract

Efficient storage of energy is the key to improving the utilization of clean energy. It is urgent to design and prepare a battery system with high specific volume, long cycle life, and fast charge–discharge characteristics. Metal-organic frameworks (MOFs) and their derivative materials have both the functional characteristics of metal ion host and organic ligand guest and have the advantages of large surface area, adjustable pores, structure, and composition. They can be directly applied, and they can be compounded to derive specific structural materials, showing unique advantages and application prospects in energy conversion and storage applications. This paper is mainly based on MOFs and their derivative materials, focusing on lithium-ion batteries with high specific energy, environmental friendliness, and large-scale energy storage. The optimization and application of MOFs and their derivatives in the microstructure and composition control of lithium-ion battery electrode materials are discussed in terms of preparation methods and battery performance, which is conducive to constructing electrode materials with abundant active sites and improving the charge transport movement of electrode materials. In general, MOFs have a very good performance improvement effect on the electrode materials of lithium-ion batteries.
