 Abstract aqueous ZNI on batteries have attracted increasing research interest due to their high energy density and low cost. However, they face several challenges such as dendrite growth, ZN corrosion, cathode material degradation, limited temperature adaptability, and electrochemical instability. We propose a novel hybrid electrolyte composed of dimethylacetamide and trimethylphosphate to address these issues. This hybrid electrolyte reduces water activity, thereby reducing ZN corrosion and extending the electrochemical stability window. Additionally, it increases the operating temperature range of the battery. Furthermore, our simulations show that this hybrid electrolyte can reduce lattice strain on the NAV308.1.5820 cathode, thus prolonging its lifespan. Overall, this work demonstrates how the use of a hybrid electrolyte can improve the performance of aqueous ZN ion batteries.
