Electrochemical behaviors of Zn in various concentrations of K₂CO₃ and KOH containing 5 M K₂CO₃ (M = mol dm⁻³) aqueous solutions (carbonate-based electrolytes) have been investigated. The electrochemical reactions of Zn in diluted K₂CO₃ and KOH containing 5 M K₂CO₃ were suppressed while they were activated in concentrated K₂CO₃. In the point of view of the ratio of the cathodic charge q_c to the anodic q_a and Zn oxidation current, 0.5 M KOH containing 5 M K₂CO₃ showed the best performance among all examined electrolytes. The dendritic growth of Zn was not observed during redox cycles in the carbonate-based electrolytes.
