Zinc is the most widely used material for battery electrodes because of its low potential (giving rise to a high cell potential), excellent reversibility (rapid kinetics), compatibility with aqueous electrolytes, low equivalent weight, high specific capacity and volumetric capacity density, abundance, low cost, low toxicity, and ease of handling.
Zinc metal electrodes are strongly influenced by the electrolyte environment in which they operate. Traditionally, most commercial zinc electrodes have been used in combination with concentrated alkaline electrolytes like KOH or saline near-neutral electrolytes like ZnCl 2 or NH 4 Cl.
Zinc-ion batteries (ZIBs) have recently attracted attention due to their safety, environmental friendliness, and lower cost, compared to LIBs. They use aqueous electrolytes, which give them an advantage over multivalent ion batteries (e.g., Mg 2+, Ca 2+, Al 3+) that require more complex electrolytes.
Besides designing innovative zinc electrodes, it is suggested that changing the composition and chemistry of electrolytes is possible; therefore, various electrolyte additives are being invented to stabilize the performance of zinc batteries.
Each additive produces a distinct crystallographic orientation and surface texture, where the electrodeposited zinc using organic additives all exhibit 6–30 times lower corrosion currents, lower float currents and higher capacity retentions than the commercial zinc foil in the hybrid Zn/LiMn 2 O 4 aqueous battery (Fig. 27 a).
Moreover, large redox potential of Zn equal to − 0.763 V against standard hydrogen electrode (SHE), avoidance of zinc dendrites, huge volumetric energy density, and long life cycle are also an additional features of zinc-ion batteries .
