Ammonium vanadate cathode materials with enhanced Zn storage by the optimization of electrolytes

Abstract

Rechargeable metal ion batteries have been alternatives to traditional fossil fuels in the past decade. Thereinto, aqueous zinc-ion batteries (AZIBs) have attracted widespread attention due to their high theoretical capacity, irreplaceable safety and fast reaction kinetics. Herein, we synthesize NH4V4O10 (NHVO) assemblies consisting of many nanobelts by a facile hydrothermal route. The obtained product is utilized as the cathode for NHVO/Zn batteries. The cell performance can be improved by the introduction of trace Li ions into the electrolyte. This electrolyte dependent strategy can be widened to prepare other vanadium-based materials with excellent electrochemical performance.
