The typical solvation shell in conventional aqueous zinc battery is zinc coordinating with six water molecules and forming the structure of [Zn (H 2 O) 6] 2+.
In a zinc-air battery, the electrolyte saturation through taking zinc-ions from the electrode reaches the solubility limit as the zinc oxide starts to get precipitated on the surface of the zinc electrode. Consequently, a film is formed on the anode, preventing it from further discharge and influencing the battery’s performance.
The recent new reported solvation shells are helping researchers to better learn the electrolyte design principles of zinc-ion batteries. The role of zinc ions, solvents, anions or additives in the solvation structure and derived SEI that are applied to regulate electrolyte and battery behavior are gradually been explored and determined.
Even the organic molecule additives may change solvation structure to stabilize the electrolyte, some of them such as hydroxyl solvents may become volatile, resulting in increased battery safety risks and low thermal stability. Blindly pursuing high performance at the expense of the safety of the original zinc-ion battery is not recommended.
As the transfer medium of zinc battery, electrolyte not only has a great impact on the cycle life and specific capacity of the battery, but also directly determines the safety performance, redox mechanism, high or low temperature performance, electrochemical stable potential windows (ESPW) and so on.
A typical strategy is to modify the electrolyte concentration of zinc batteries. The conventional aqueous electrolytes (typically used at 1–2 m ZnSO 4 concentration) can guarantee balanced amounts of anions and solvent, allowing good ionic conductivity and moderate electrochemical potential window for battery operation.

However, though the zinc ion can diffuse through the solution, there is nowhere for the two electrons to go, so they are trapped within the electrode. This excess charge opposes further oxidation—it becomes more and more difficult to force more charge into the electrode. For this reason, zinc electrodes do basically nothing in neutral ...
