Vanadium Oxide Cathode Coinserted by Ni and NH for High-Performance Aqueous Zinc-Ion Batteries.

Vanadium-based oxides have garnered significant attention as cathode materials for aqueous zinc-ion batteries (AZIBs) because of their high theoretical capacity and low cost. However, the limited reaction kinetics and poor long-term cycle stability hinder their widespread application. In this paper, we propose a novel approach by coinserting Ni and NH ions into VO·3HO, i.
