Review on the recent development of Li_(3)VO_(4)as anode materials for lithium-ion batteries

摘要

Among the various anodes,Li_(3)VO_(4)is a potential intercalation kind anode used in lithium-ion batteries(LIBs)that exhibits safer discharge voltage and higher capacity than graphite,a lower voltage plateau than Li_(4)Ti_(5)O_(12),and smaller volume difference in the Li^(+)intercalation/deintercalation process than metals and alloys.However,the comparatively low electronic conductivity,low initial coulombic efficiency(ICE)and serious capacity decay make the Li_(3)VO_(4)anode unviable when it comes to practical implementation.Therefore,this paper reviews the research progress of Li_(3)VO_(4)in recent years,mainly including the strategies of developing different synthesis methods to construct unique morphology,through coating,compositing or elemental doping to increase the ICE,electronic conductivity and the cycle constancy.Moreover,the application of Li_(3)VO_(4)anode materials in other energy storage systems is summarized.Lastly,the development prospect and challenge of Li_(3)VO_(4)anodes are discussed.
