Applications of Zeolitic Imidazolate Frameworks(ZIFs)and Their Derivatives in Lithium-Ion Battery Anode Materials
As a key energy storage device,lithium-ion batteries play a vital role in renewable energy and electric vehicles.Zeolitic imidazolate frameworks(ZIFs)are a typical type of MOFs material,and their controllable pore structure and abundant surface functionality make them one of the ideal choices for anode materials in lithium-ion batteries.This article summarizes the application of ZIFs materials and their derivatives in lithium-ion battery anode materials.Firstly,directly using the zeolite-like imidazole ester framework as a negative electrode material for lithium-ion batteries can significantly alleviate the volumetric expansion stress of the electrode material during charging and discharging due to its porous structure,which is beneficial for the storage and transport of lithium ions,thereby improving the cycle life and stability of the battery.Secondly,through heat treatment and chemical conversion,ZIFs can be transformed into derivative forms such as porous carbon materials,metal oxides,metal halides,metal phosphides,and silicon composites.These forms not only retain the structural advantages of ZIFs but also possess their own chemical properties,demonstrating excellent performance in battery applications.Among them,this article focuses on the application of ZIFs metal oxides and metal halides,which have become strong candidates for high-energy density anode materials due to their high theoretical capacity and good electrochemical performance.In addition,although ZIFs and their derivative materials face some challenges in practical applications,such as high cost and complex preparation processes,these problems are expected to be gradually solved with further research and technological progress.By optimizing the preparation process and material design,the electrochemical performance and practical application value of ZIFs and their derivative materials can be further improved.In summary,the application of zeolite-like imidazole ester framework and its derivatives in lithium-ion battery anode materials shows great promise.
