Recent advances in metal-organic frameworks for electrochemical performance of batteries

Energy shortage hinders the rapid development of today’s society,and the emergence of electronic travel equipment alleviates this phenomenon to a certain extent.The batteries are the energy storage part of electric equipment.Metal-organic frameworks(MOFs)are a fresh sort of porous crystal materials with controllable structure,large specific surface area,and adjustable pore size.MOFs are good electrode materials,which are used to make a variety of friendly environment,long cycling life and superior energy density of new batteries.Furthermore,MOFs are also used in separators and electrolytes,which have a lot of application space in batteries.In this review,the up-to-date research advance of MOF materials in various kinds of batteries(lithium-ion batteries,lithium oxygen batteries,lithium sulfur batteries,zinc-ion batteries,potassium-ion batteries,etc.)is reviewed.Moreover,concisely introduced several conventional synthesis approaches of MOFs.Finally,Perspectives and directions on the future improvement of MOF in energy storage devices are proposed for meeting the requirement of practical applications.
