摘要:

锂离子电池是一种新型的二次能源,担负着未来电池发展的新方向,广泛应用于人们的生产生活中,但商品化锂离子电池的能量密度和循环性能目前还难以满足生产力发展的需求。人们在探寻性能更优的锂离子电池电极材料时,发现具有多孔以及大比表面积特性的金属有机骨架材料(MOFs)及其相应的衍生物相比传统电极材料,在提高锂离子扩散速率、缓解体积变化和保证循环稳定性方面具备更好的优势,因此,MOFs及其衍生物是一种非常有潜力的锂离子电池电极材料。为此,本文主要通过对近期相关文献的探讨,对MIL、MOF、ZIF和普鲁士蓝系列MOFs及其衍生物作为锂电池负极和正极的研究进行详细综述,着重介绍了上述材料的制备方法以及锂离子电池容量提高的影响机理,得出MOFs及其衍生物较好的电荷负载能力和多孔结构的特点,是相对于传统锂离子电池电极性能更优的原因。最后指出针对目前MOFs类电极材料遇到的最大问题,未来应在与其他导电材料复合,机械化学合成方法和不依赖昂贵材料三个发展方向进行努力,有望实现MOFs类锂离子电池电极材料的商业化发展。

Abstract:

The lithium-ion battery is a new type of secondary energy storage device, representing a new direction of future battery development, and is extensively used in production and daily life. However, the energy density and cycling performance of the commercial lithium-ion batteries remain insufficient to satisfy the demands of productivity development. On seeking better-performing electrode materials for lithium-ion batteries, metal–organic framework materials (MOFs) with their porous structures and high specific surface areas as well as their corresponding derivatives exhibit advantages over traditional electrode materials because of their improved lithium-ion diffusion rate, reduced volume changes, and increased cycling stability, which make them highly promising lithium-ion battery electrode materials. Therefore, this study mainly reviews the MIL, MOF, ZIF, and Prussian blue series MOFs and their derivatives as negative and positive electrodes of lithium batteries based on the discussion of recent related literature. The preparation methods of the above materials and the mechanism of capacity improvement of the lithium-ion batteries are also emphasized. The influence mechanism of the increase in the lithium-ion battery capacity shows that the charge loading capacity and porous structures of MOFs and their derivatives make them superior to conventional lithium-ion battery materials. Finally, based on the most significant issues currently associated with the MOF electrode materials, future research should focus on three development directions, i.e., composites with other conductive materials, mechanochemical syntheses, and the use of inexpensive materials, to realize the commercial development of MOF electrode materials for lithium-ion batteries.
