Abstract
Among the various anodes,Li3VO4 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 Li4Ti5O12,and smaller volume difference in the Li+ intercalation/deintercalation process than met-als and alloys.However,the comparatively low electronic conductivity,low initial coulombic efficiency(ICE) and serious capacity decay make the Li3VO4 anode unviable when it comes to practical implemen-tation.Therefore,this paper reviews the research progress of Li3VO4 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 Li3VO4 anode materials in other energy storage systems is summarized.Lastly,the development prospect and challenge of Li3VO4 anodes are discussed.
