This Review critically discusses recent breakthroughs and future challenges in research on polyoxovanadate energy materials. The use of polyoxovanadates in batteries, redox-flow batteries, light-driven catalysis, and electrocatalysis is described together with an outlook on emerging themes and areas of future application.

Which nib and Lib cathode materials are used in a decavanadate prototype?

In addition to studies using the decavanadate prototype, other common POVs such as K 5.72 H 3.28 [PV 14 O 42], 64 K 7 [NiV 13 O 38], 65 K 7 [MnV 13 O 38], 66 and the carbonate-templated Li 7 [V 15 O 36 (CO 3)] 67, 68 have also been used as NIB and LIB cathode materials and showed promising performance.

What is a vanadium-chromium RFB (V/Cr RFB)?

In this work, combining the merits of both all-vanadium and iron-chromium RFB systems, a vanadium-chromium RFB (V/Cr RFB) is designed and fabricated. This proposed system possesses a high theoretical voltage of 1.41 V while achieving cost effectiveness by using cheap chromium as one of the reactive species.
