“…70 % [48,49]. Different types of gels or binders have been reported, such as polytetrafluoroethylene (PTFE) [50,51], sago [49,52], carbopol gel [53], and a tapioca binder [54]. Notwithstanding its advantages in terms of porosity enhancement, the use of gelling agents increases both electrolyte resistance and manufacturing costs.…”

Metal-air batteries are becoming of particular interest, from both fundamental and industrial viewpoints, for their high specific energy density compared to other energy storage devices, in particular the Li-ion systems. Among metal-air batteries, the zinc-air option represents a safe, environmentally friendly and potentially cheap and simple way to store and deliver electrical energy for both portable and stationary devices as well as for electric vehicles. Zinc-air batteries can be classified into primary (including also the mechanically rechargeable), electrically rechargeable (secondary), and fuel cells. Research on primary zinc-air batteries is well consolidated since many years. On the contrary, research on the electrically rechargeable ones still requires further efforts to overcome materials science and electrochemical issues related to charge and discharge processes. In addition, zinc-air fuel cells are also of great potential interest for smart grid energy storage and production. This review aims to report on the latest progresses and state-of-the-art of primary, secondary and mechanically rechargeable zinc-air batteries, and zinc-air fuel cells. In particular, this review focuses on the critical aspects of materials science, engineering, electrochemistry and mathematical modeling related to all zinc-air systems.

“…These additives can reduce the concentration of the zinc oxidation products and improve electronic conductivity and current distribution [14]. Binders or gels, such as sodium silicate [19], tapioca [20], polytetrafluoroethylene [21,22], Carbopol gel [23,24], and sago which is a starch extracted from palm stems [25], were used to increase the active material utilization and effective surface area in zinc electrode. Addition of sodium silicate as binder was reported to increase battery performance [19].…”

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.

“…Recent researches have shown that biomass‐derived materials, that is, natural organic macromolecules or modified ones, can be employed as electrode binder. Extensively studied biomass‐derived binders include sodium carboxymethyl cellulose (CMC), cyclodextrin, natural gum, and agar or their mixtures . These environmentally friendly binders have shown great success in silicon and sulfur electrode because they can offer desired properties to meet the additional demands of these newly emerged electrodes.…”
