In this review, we will discuss the application of energy storage and electrocatalysis using a series of vanadium oxides: the mono-valence vanadium oxides, the mix-valence Wadsley vanadium oxides, and vanadium-based oxides. Related parameters of different vanadium oxides in LIBs are presented in Table 13.1.
Vanadium-based alloys are potential materials for hydrogen storage applications in Remote Area Power Supply (RAPS) and Movable Power Supply (MPS). In this study, V 80 Ti 8 Cr 12 alloys are tailor-made to meet the RAPS and MPS working conditions (293–323 K and 0.2–2 MPa).
Furthermore, and importantly, a quite promising solution method for the practical commercialized applications of vanadium oxides cathode materials in the future is proposed, i.e., fabricating the “vanadium oxides-based cathode/solid electrolyte/Li metal anode-type” all solid-state secondary-ion batteries.
As a critical practical material, vanadium oxide and their derivatives have shown outstanding applications in different fields, for example, catalysis [ 19 ], sensors [ 20, 21, 22, 23 ], electrochromic appliances [ 24 ], electric actuators, etc [ 25 ].
As one group of promising high-capacity and low-cost electrode materials, vanadium-based oxides have exhibited an quite attractive electrochemical performance for energy storage applications in many novel works. However, their systematic reviews are quite limited, which is disadvantageous to their further development.
However, all the samples used in this study showed rapid hydrogen absorption, suggesting that very little amount of vanadium oxide may not have a significant effect on the alloy's ability to store hydrogen. Hence, the lattice contraction could be the key factor affecting the hydrogen storage capacity.
