Application of Metal-Organic Framework in Electrode Materials of Lithium-Ion Batteries

锂离子电池具有能量密度高、无记忆效应、低成本、寿命长等优点,被认为是便携式电子设备和电动汽车最有前途的储能技术.金属-有机框架(MOFs)具有超高孔隙率、功能多样性、结构可控及易制备等独特优点,被广泛应用在异相催化、电化学储存与转化、气体吸附和分离等领域中.对MOFs直接作为锂离子电池负极材料及正极材料的研究进展进行了阐述,重点总结了MOFs衍生材料(多孔碳材料、单一金属氧化物、多组分金属氧化物、磷化物等)应用于锂离子电池电极材料中的合成方法、结构及电化学性能.最后对MOFs及其衍生材料在锂离子电池正极和负极材料的发展方向进行了展望,为新型电极材料的下一步开发方向提供一定的思路和建议.

Due to the advantages of high energy density,no memory effect,low cost and long life,lithiumion batteries(LIBs) are considered to be the most promising energy storage technology for portable electronic devices and electric vehicles. Metal-organic frameworks(MOFs)have unique advantages such as ultra-high porosity,functional diversity,controllable structure and easy preparation,which are widely used in the fields of heterogeneous catalysis, electrochemical storage and conversion, gas adsorption and separation. In this paper,firstly it summarizes the direct application of MOFs to lithium-ion battery anode materials and the research progress of lithium-ion battery cathode materials,mainly focusing on the review and summary of the synthesis method,structure and electrochemical performance of MOFs derived materials(porous carbon materials, single metal oxides, multi-component metal oxides,etc.). Finally, the development direction of MOFs and their derivatives in lithium-ion battery cathode and anode materials is prospected, and certain ideas and suggestions are provided for the next development direction of new electrode materials.
