Summary Aluminum-air fuel cells attract more attention because of their high specific energy, low cost, and friendly environment. However, the problems of hydrogen evolution corrosion and low anode efficiency of aluminum-air fuel cells remain unresolved. Herein, we propose an aluminum-air fuel cell using a mesh-encapsulated anode, where the energy redistribution can be achieved and the discharge performance of the fuel cell can be highly improved. The results show that the highest inhibition efficiency is 73.930% when the aluminum plate is immersed in 6 M potassium hydroxide solution containing 100% zinc oxide. The highest anode efficiency is up to 61.740% when the fuel cell using a mesh-encapsulated anode is discharged at 20 mA/cm 2 , which is more than 2 times than that of no mesh, and the highest capacity can reach 1839.842 mAh/g, which is 101.623% higher than before optimization. Thus, our studies are very instructive for the large-scale application of aluminum-air fuel cells.

“…The SBs provide high power density and a specific energy of electricity storehouse systems in most EV implementations because of cell technologies' high technologies and competitive costs [170,171]. For different EVs, the SB can be made of a zinc-halogen category (Zn-Cl 2 , Zn-Br 2 ), metal-air category (Fe-Air [65,66], Al-Air [64,65], Zn-Air [136][137][138][139][140][141][142][143]), sodium-beta (Na-S, Na-NiCl 2 ), lithium high temperature (Li-AlFeS, Li-AlFeS 2 ), medium temperature lithium, such as lithium-polymer (Li-polymer) and lithium-ion (Li-ion), and batteries family, such as Li-NiCoAlO 2 , LiNixMnyCozO 2 , LiFePO 4 , and LiCoO 2 cathodes. Compared to other Li-ion batteries, Li-S offer higher specific energy, better safety, and a slightly wider operating temperature.…”

The increase of electric vehicles (EVs), environmental concerns, energy preservation, battery selection, and characteristics have demonstrated the headway of EV development. It is known that the battery units require special considerations because of their nature of temperature sensitivity, aging effects, degradation, cost, and sustainability. Hence, EV advancement is currently concerned where batteries are the energy accumulating infers for EVs. This paper discusses recent trends and developments in battery deployment for EVs. Systematic reviews on explicit energy, state-of-charge, thermal efficiency, energy productivity, life cycle, battery size, market revenue, security, and commerciality are provided. The review includes battery-based energy storage advances and their development, characterizations, qualities of power transformation, and evaluation measures with advantages and burdens for EV applications. This study offers a guide for better battery selection based on exceptional performance proposed for traction applications (e.g., BEVs and HEVs), considering EV’s advancement subjected to sustainability issues, such as resource depletion and the release in the environment of ozone and carbon-damaging substances. This study also provides a case study on an aging assessment for the different types of batteries investigated. The case study targeted lithium-ion battery cells and how aging analysis can be influenced by factors such as ambient temperature, cell temperature, and charging and discharging currents. These parameters showed considerable impacts on life cycle numbers, as a capacity fading of 18.42%, between 25–65 °C was observed. Finally, future trends and demand of the lithium-ion batteries market could increase by 11% and 65%, between 2020–2025, for light-duty and heavy-duty EVs.

“…[10] Specifically, atmospheric oxygen from the hydrophobic side is reduced to dissolved hydroxide ions during ORR and the hydroxide ions in electrolyte are oxidized to oxygen during OER from the hydrophilic side to the hydrophobic side. [11] The bifunctional electrocatalysts are supposed to be loaded at the asymmetric interface between the hydrophobic side and the hydrophilic side to perform the maximum electrocatalytic efficiency. [12] Therefore, asymmetric design of the air cathode and electrocatalyst loading on the asymmetric interface are essential to realize high-efficiency ORR and OER in working ZABs.…”
