“…Some of them are either expensive or toxic and not environmentally friendly limiting their use in batteries. One of the few organic materials which is nontoxic and cheap is polyethylene glycol (PEG) [26,27]. Corrosion inhibition capability of PEG was found to be greater than that of polyoxyethylene alkyl phosphate ester acid form when used in zinc electrode [27,28].…”

Prismatic Nickel-Zinc (NiZn) batteries with energy densities higher than 100 Wh kg −1 were prepared using Zn electrodes with different initial morphologies. The effect of initial morphology of zinc electrode on battery capacity was investigated. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) reveal that initial morphology of zinc electrode changes drastically after a few charge/discharge cycles regardless of initial ZnO powder used. ZnO electrodes prepared using ZnO powders synthesized from ZnCl 2 and Zn(NO 3 ) 2 lead to average battery energy densities ranging between 92 Wh kg −1 and 109 Wh kg −1 while using conventional ZnO powder leads to a higher energy density, 118 Wh kg −1 . Average discharge capacities of zinc electrodes vary between 270 and 345 mA g −1 , much lower than reported values for nano ZnO powders in literature. Higher electrode surface area or higher electrode discharge capacity does not necessarily translate to higher battery energy density.

“…It has been found that the surfactants containing polyoxyethylene group are more effective than other surfactants as zinc corrosion inhibitors. [20][21][22][23] To form a protective layer on zinc, sufficient amount of surfactant needs to be used, which inevitably increases the internal resistance and deteriorates the discharge performance of zinc batteries.…”

The combined use of indium and polysorbate 20 (Tween 20) was considered as a new inhibition technique for zinc corrosion. Zn and Zn-In alloy coatings were prepared by electrodeposition and their morphology and composition were characterized by scanning electron microscopy (SEM) and inductively coupled plasma atomic emission spectrometry (ICP-AES). The corrosion inhibition effect of indium and Tween 20 on zinc was investigated by polarization curves and electrochemical impedance spectroscopy (EIS). The corrosion inhibition efficiencies obtained from Tafel and EIS analyses are well in agreement. Zinc corrosion can be inhibited to some extent by the individual use of indium and Tween 20 and higher corrosion inhibition efficiency can be obtained by the combined use of indium and Tween 20.

“…Without the use of a gelling agent, the diffusion of Zn ions away from the electrode leads to a rapid decrease in capacity retention at the anode in every cycle. Polyacrylic acid (PAA) [2] is the typical gelling agent used in Zn-air batteries. It is chemically stable in concentrated base solutions, where it becomes the counter base, polyacrylates.…”

The gelling agent used in Zn-air cells plays a role in improving battery life. It prevents the evaporation of water and diffusion of Zn 2 + ions away from the current collector. Additional functionality was incorporated by replacing some of the gelling agents with new materials. Alcohols with moderate viscosity, namely maltose, sucrose, poly ethylene glycol 600, and 2-hydroxyethyl cellulose, were used to replace some gelling agents in this work. Among these alcohols, poly ethylene glycol 600 and 2-hydroxyethyl cellulose improved the cycle life of full cells. This improved cycle life was attributed to the inhibition of water electrolysis and the improved cycle life of the anode.
