Abstract

Aqueous rechargeable zinc-ion batteries (AZIBs) have drawn enormous attention in stationary applications due to their high safety and low cost. However, the search for new positive electrode materials with satisfactory electrochemical performance for practical applications remains a challenge. In this work, we report a comprehensive study on the use of the vanadium tellurate (NH₄)₄{(VO₂)₂[Te₂O₈(OH)₂]}·2H₂O, which is tested for the first time as a cathode material in AZIBs.
