New Mexico State University Solar Energy, Luo1 - review paper

In this review, we summarized the recent progresses using niobium-based oxide as electrodes for batteries (LIBs, sodium-ion batteries (SIBs), and vanadium redox flow batteries (VBRs), SCs, and fuel cell applications. Moreover, crystal structures, charge storage mechanisms in different crystal structures, and the electrochemical performances in terms of their specific capacitance/capacity, rate capability, and cycling stability of niobium-based oxide are discussed. Insights into the future research and development of niobium-based oxide compounds for the next generation electrochemical devices are also presented. We believe that this review will be beneficial for the research scientists and graduate students who are searching for the promising electrode materials for batteries, SCs, and fuel cells.
