摘要
磷酸盐系锂离子电池正极材料因导电性差和Li+扩散系数低等原因,发展受到限制.金属有机骨架(MOF)具有比表面积大、活性位点丰富等优点.通过MOF前驱体来提升磷酸盐系正极材料电化学性能有很高的可行性.从用MOF或MOF衍生物通过制备、掺杂和表面改性等 3 种不同方法改性正极材料的角度,综述近年来MOF基磷酸盐系锂离子电池正极材料的研究进展,并对MOF应用于锂离子电池正极材料的发展方向进行展望.
Abstract
The development of phosphate-based Li-ion battery cathode materials has been limited by factors such as poor electrical conductivity and low Li+diffusion coefficient.Metal-organic framework(MOF)offers advantages such as a large specific surface area and rich active sites.MOF precursor shows great potential for enhancing the electrochemical performance of phosphate-based cathode materials.The research progress in MOF-based phosphate-based Li-ion battery cathode materials in recent years is reviewed from the perspective of using MOF or MOF derivatives to modify cathode materials by three different methods:preparation,doping and surface modification.The development direction of MOF application in cathode materials for Li-ion battery is also prospected.
