The development of high-performance cathode material is the key to realize commercial application of zinc-ion batteries (ZIBs). Vanadium-based materials have been used as cathode candidate for ZIBs due to their...
In this paper, we found that (NH4)2V4O9 undergo an electrochemical activation process in the first charging process at ~1.4 V (vs. Zn2+/Zn), leading to a significant improvement of capacity and...
NaV6O15 microflowers were synthesized as a stable cathode material for aqueous zinc ion batteries, which show a high specific capacity and excellent long-term cycling performance.
