“…As mentioned above, the PPy films are dedoped and the concentration of reduced PPy becomes considerable after enough immersion, thus the current of PPy oxidation occurs at anodic polarisation process. The dedoping process of PPy will also cause release of DBS 2 , an effective inhibitor for metal corrosion, 43,44 which is similar to the proposals in literatures where it is reported that the released anions have a positive effect on improving protection of the films. 6,21,[45][46][47] Therefore, metal corrosion can be thought as neglectable just during short time immersion, which is demonstrated in Fig.…”

The electrosynthesis process of conducting polymer on stainless steel was investigated and a two-step process was adopted to obtain polypyrrole (PPy) films at low potentials. The effects of applied potentials on the electrochemical, structural and protective properties of PPy films have been explored using scanning electron microscopy, infrared spectroscopy, cyclic voltammetry, open circuit potential and potentiodynamic polarisation. Films electrodeposited at lower potentials have more homogeneous morphology and less overoxidation. The electroactivities decrease as applied potentials increase. Polypyrrole films exhibit effective inhibition of corrosion for stainless steel in 3?5%NaCl solution. Applying lower potential for the synthesis improves the anticorrosive efficiency of PPy film. The anodic current during polarisation process for stainless steel/PPy is mainly ascribed to the dissolution of stainless steel at pinhole defects for initial immersion, and to PPy oxidation after short time immersion.

“…8a and b, increasing HPB and particle concentration in electrolyte have small effects on the size of the deposited Ni matrix grains. The effect of the surfactant concentration has reported to be resulted in decreasing of the matrix grain size even with little additions [33]; however, high amounts of surfactant caused increase in the size of Ni droplets. In fact, the parameters may affect the size of the Ni droplets are temperature, mixing and current density.…”

“…However, in more diluted alkaline electrolyte, the use of organic additives such as surfactants is suggested. 132 Surfactant compounds consist of 2 parts: a hydrophilic and a hydrophobic part, and they are used for different purposes, including wetting, emulsifying, dispersing, foaming, and increasing the inhibiting properties of electrodeposition process. The mechanism of organic additives is based on their physical adsorption on preferential areas where the dendrite grows ( Figure 5C).…”

“…This type of additive is generally added to the electrolyte instead of to the zinc electrode. 132,140 These molecules adsorb at the solid/solution interface and form surfactant aggregates on the electrodes. 132,133 They are also effective for minimizing the zinc diffusion into the bulk of the aqueous alkaline electrolyte and thus retaining the zinc discharge products inside the porous structure, and recomplexing the zincate ions.…”

Summary Electricity will increasingly be produced from sources that are geographically decentralized and/or intermittent in their nature. In consequents, there is an urgent need to increase the storage of energy to guarantee the continuity of energy supply. Rechargeable zinc‐air battery is a promising technology due to the high theoretical energy density and the abundant and environmentally benign materials that are used. In the state of the art, the information about secondary zinc anode for rechargeable zinc‐air batteries is scarce. The main development of the technology has been lately concentrated on the bifunctional air electrodes while the used zinc anode is mainly based on a planar zinc electrode providing low specific energy densities for the full system. This overview compiles the available information in the literature regarding the development and manufacturing of zinc anodes for electrical rechargeable batteries applications, where secondary porous zinc electrodes are generally desired. In this context, the zinc‐based anode electrode composition (namely, active material, binder, conductive material, current collector, and additives), pretreatments, and processing techniques are described and their impact on the zinc anode performance analyzed.
