Unlocking Zn Storage Performance of Ammonium Vanadate Nanoflowers as High-Capacity Cathodes for Aqueous Zinc-ion Batteries via Potassium Ion and Ethylene Glycol Co-Intercalation Engineering

Ammonium vanadate (NH4V4O10) is a highly promising cathode for aqueous zinc ion batteries (AZIBs) due to its tunable layered structure and high specific capacity; however, limited active sites, poor kinetics...
