金属有机框架基磷酸盐系正极材料研究进展OA北大核心CSTPCD

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.
