“…Low float current density is preferred because of less energy required. [24,42] The variation in the peak intensities between literature and the obtained data of commercialz inc may be due to the differente xperimental procedures since our XRD were taken on the ready-to-use Zn battery anodes. Theb attery with the anode electroplated withoutt he additive presents the highest float current.…”

The synthesis of novel zinc electrodes has been successfully implemented by using the electroplating method with the aid of inorganic additives in the electroplating solution. The selected inorganic additives are indium sulfate, tin oxide, and boric acid. From X-ray diffraction results, these synthesized zinc electrodes prefer (002) and/or (103) crystallographic orientations, representing basal morphology and high resistance to dendrite growth. The corrosion rates of these electroplated zinc samples decrease as much as 11 times smaller than the corrosion rate on zinc foil when the zinc materials are in contact with the aqueous electrolyte of a rechargeable hybrid aqueous battery (ReHAB). The ReHABs employing these anodes exhibit up to a threefold decrease in float charge current density after a seven-day constant-voltage charging at 2.1 V versus Zn /Zn. Furthermore, the capacity retention is up to 15 % higher than the performance of battery containing commercial Zn after 1000 cycles of charge-discharge. The significant advancements are attributed to the careful preparation of the anode, which contains appropriate crystallographic orientation and morphology.

“…Tin concentrations of less than 2 mg/L considerably reduce the current efficiency, but the reduction levels off at greater concentrations. There are conflicting reports as to whether tin enhances or inhibits hydrogen evolution [38,35]. While As (III) had no effect on the current efficiency and does not alter deposit morphology or orientation, the presence of small concentrations of As (V) (less than 5 mg/1) are detrimental, causing changes in morphology and orientation and a dramatic decrease in current efficiency [39].…”

The removal of cobalt from zinc electrolyte has been a focus of electrometallurgical research for over 20 years. This survey reviews the literature on cobalt cementation as well as zinc electrowinning and hydrogen evolution in the interest of characterizing the factors which are important in cobalt cementation by zinc dust and developing an improved purification process. The effect of speciation, the solubility of zinc hydroxide and zinc sulfate, temperature, pH, and the concentrations of reacting species, impurities, and catalytic agents are all investigated.

“…Cadmium [7] did not affect the growth or orientation of the zinc deposit but reduced the deposit grain size. Small concentration of germanium [6,14,15] and tin [16] drastically reduced the CE and induced changes in cathodic polarization, deposit morphology and crystallites orientation. Antimony [1,2,[17][18][19] was recognized as one of the most deleterious impurities for zinc electrodeposition whose presence in the electrolyte produced spongy and dark deposits.…”

The effects of ionic liquid additive 1-butyl-3-methylimidazolium hydrogen sulfate- [BMIM]HSO 4 on the current efficiency (CE), surface morphology, and crystallographic orientations during zinc electrodeposition from acidic sulfate solutions containing some common impurities such as copper, iron, cobalt, nickel, and lead were investigated. The results indicated that all the metallic impurities studied exerted a deleterious effect on the zinc electrodeposition process by decreasing the CE, influencing the purity, and inducing changes in morphology of the cathodic deposits. The addition of [BMIM]HSO 4 was observed to relieve the harmful effects of these impurities to some extent, and led to reduce the impurity content in the zinc deposits and improve the CE and the quality of the cathodic deposits. The data obtained from X-ray diffraction revealed that the presence of these impurities alone and in combination with [BMIM]HSO 4 did not change the structure of the electrodeposited zinc but affected the crystallographic orientation of the crystal planes.
