“…Zinc samples for weight loss measurements were prepared as reported in references [4,18,19]. Zinc sheets (99.9985%, 7 9 7 9 0.24 mm 3 ) were immersed in 3.6 wt% dilute hydrochloric acid under ultrasonication for 5 min to remove the surface oxide that was formed in air during transportation, rinsed with doubly distilled water and degreased with acetone.…”

“…Owing to its high activity, zinc tends to be corroded in alkaline solution, resulting in inevitable capacity loss of the batteries. The most effective way to solve this problem is to introduce corrosion inhibitors to the electrolyte solution [4][5][6][7][8]. In the past, mercury was used as a successful inhibitor because it can enhance the over-potential of hydrogen evolution and thus inhibit the corrosion of zinc.…”

Polyethylene glycol 600 (PEG 600) and polysorbate 20 (Tween 20) were used as a composite corrosion inhibitor of zinc in alkaline solution for the first time. The effects of the composite and individual inhibitors on corrosion inhibition of zinc were evaluated by weight-loss analysis and electrochemical methods including potentiodynamic, potentiostatic, and electrochemical impedance spectroscopic measurements. It was found that there was a synergistic effect between PEG 600 and Tween 20 on corrosion inhibition of zinc. The corrosion inhibition efficiency of the composite inhibitor, 500 ppm PEG 600 ? 500 ppm Tween 20, was 89%, much higher than that of the individual inhibitor, 1000 ppm Tween 20 (71%) or 1000 ppm PEG 600 (55%). The battery (Zn/MnO 2 ) discharge performance tests showed that the composite inhibitor reduced the self-discharge of zinc anode more effectively than the individual inhibitor. The synergistic mechanism between PEG 600 and Tween 20 was discussed.

“…There is an extensive literature on the effect of metallic ions, e.g. Bi 3+ , Pb 2+ , on Zn deposition in the alkaline electrolyte [3][4][5][6][7]. Even though it is known that Bi 3+ and Pb 2+ additives effectively inhibit Zn dendritic growth and extend the cycle life of the Zn electrode, no systematic study has been carried out on the effects of these metallic ions on other aspects of the electrochemical behavior of the Zn electrode, e.g.…”

The effect of stannous ions as an electrolyte additive on the electrodeposition characteristics of Zn was investigated by chronoamperometry, the potential-step method and cyclic voltammetry. The chronoamperometry measurements showed that the addition of stannous ions inhibited the dendritic growth of Zn deposits. SEM observation also revealed that the Zn deposit was in the form of compact cylinders with rounded tops that consist of many small crystallites, rather than the classical dendrites with side branches. The inhibition effect of Sn 2+ on the very initial electrocrystallization of Zn was not a substrate effect. The 0.17 V difference in reduction potential between Zn and Sn resulted in the codeposition of Sn and Zn. An interruption effect was proposed to illuminate the inhibition effect of Sn 2+ on the formation of Zn dendrites. Furthermore, Sn 2+ additive was found to suppress the corrosion reaction of Zn by 87% in the Sn 2+ -containing zincate electrolyte, comparing to that in the blank zincate electrolyte.

“…However, the problems of zinc electrode like self-discharge [3,4] and dendritic growth [5][6][7] resulting in gradual capacity loss and short cycle life of the electrode have not been overcome completely, and they become the reason why zinc secondary batteries have not been commercialized extensively [8]. Many attempts have been made to minimize the difficulties using additives in either the electrode [9][10][11] or the electrolyte [12][13][14], and still the problems remain elusive. Moreover, the additives may lower the specific power or specific energy of zinc electrode.…”
