Revitalized interest in vanadium pentoxide (V2O5) arises from two very important developments in rechargeable
batteries. One is the push on lithium-ion batteries for higher energy density batteries: using lithium metal as
anode and searching for higher capacity and high voltage cathode. Using lithium metal anode eliminates the big
obstacle for V2O5 cathode that does not come with lithium ions. V2O5 possesses the highest reversible capacity
among known cathode materials. Another is the recent intensive research for cathode materials beyond Li-ion
batteries (LIBs). In the past several years, interest in complementary alkali-ion battery technologies has seen a
tremendous resurgence. Out of the set of alternative chemistries, V2O5 has seen the most considerable and
promising gains as a cathode for Na-ion battery (NIB), Mg-ion battery (MIB), and other metal batteries. Unlike
LIBs, these systems face a set of new challenges as dictated by the properties of the transported ionic species and
the consequent effects on the electrode materials. The purpose of this review is to summarize the most
interesting or surprising phenomena, the important questions raised and next experimental and theoretical
steps to advance V2O5 cathode materials in the field of metal batteries. This review focused on selected topics
covering the influences of surface chemistry, crystallinity, doping, defects, and nanostructures on the lithiumion
intercalation properties and recent developments on other metal batteries including NIBs and MIBs. The
perspectives and remaining challenges for V2O5 based cathode materials have been discussed.
