“…The membrane would act as a conductor for the OH − ions as well as a separator for the electrolyte solution. Different membrane separator types, such as organic polymer porous membranes, inorganic membranes [46], composite membranes [47], cation-exchange membranes [48], and anion-exchange membranes (AEMs) [49] have been used in Zn-air battery applications. However, despite their early beginning and being active research topics, their development and commercialization have been hampered by several remaining challenges associated with their components, such as the metal anode (corrosion, forming passivation layers, dendritic formation, electrode deformation, and energy loss due to self-discharging), air cathode (lack of efficient catalysts for both oxygen reduction and evolution reactions, affecting electrolyte stability, and gas diffusion blockage by side reaction products), and electrolyte (side reaction with the anode, reaction with CO2 from the air, and low conductivity) [15,18] (Table 1).…”

Rechargeable alkali metal–air batteries have enormous potential in energy storage applications due to their high energy densities, low cost, and environmental friendliness. Membrane separators determine the performance and economic viability of these batteries. Usually, porous membrane separators taken from lithium-based batteries are used. Moreover, composite and cation-exchange membranes have been tested. However, crossover of unwanted species (such as zincate ions in zinc–air flow batteries) and/or low hydroxide ions conductivity are major issues to be overcome. On the other hand, state-of-art anion-exchange membranes (AEMs) have been applied to meet the current challenges with regard to rechargeable zinc–air batteries, which have received the most attention among alkali metal–air batteries. The recent advances and remaining challenges of AEMs for these batteries are critically discussed in this review. Correlation between the properties of the AEMs and performance and cyclability of the batteries is discussed. Finally, strategies for overcoming the remaining challenges and future outlooks on the topic are briefly provided. We believe this paper will play a significant role in promoting R&D on developing suitable AEMs with potential applications in alkali metal–air flow batteries.

“…synthesized high‐density iron/nitrogen‐doped carbon (Fe@N‐C) core‐shell nanoparticles with superior ORR and OER performance in alkaline electrolytes and exhibit a peak power density of 220 mW cm −2 and long cyclability over 100 cycles (600 s discharge followed by 600 s charge) . A simple method for fabricating a 5 mm inorganic microporous MCM‐41 membrane was proposed by Saputra and coworkers in 2011 . The zinc‐air cell assembled with this MCM‐41 separator in a KOH electrolyte delivered a peak power density of 32 mW cm −2 .…”

Rechargeable lithium-ion, lithium-sulfur, zinc-air, and redox-flow batteries are the most anticipated multipurpose platforms for future generations of electric vehicles, consumer devices, and portable electronics because of their high-energy density and cost-effective electrochemical energy storage. Over the past decades, a variety of novel separator membranes and electrolytes have been developed to improve rechargeable battery performance while not thoroughly addressing the issue of flammability, safety, and low cycling stability of high-energy-density batteries. This comprehensive review mainly underlines the optimization and modification of porous membranes for battery separator applications, covering four significant types: microporous separators, nonwoven mat separators, polymer electrolyte membranes, and composite membrane separators. Furthermore, the present trends in material selection for batteries are reviewed, and different choices of cathode, anode, separator, and electrolyte materials are discussed, which will also serve as key components to boost the development of next-generation rechargeable batteries.

High discharge rate zinc electrode is prepared from electrodeposition process. The electrolytic bath consists of zinc chloride as the metal source and ammonium chloride as the supporting electrolyte. The concentration of the supporting electrolyte is varied from zero until 4 M, while the concentration of zinc chloride is fixed at 2 M. The aim is to produce a porous zinc coating with an enhanced and intimate interfacial area per unit volume. These characteristics shall contribute towards reduced ohmic losses, improved active material utilization, and subsequently producing high rate capacity electrochemical cell. Nitrogen physisorption at 77 K is used to measure the BET surface area and pore volume density of the zinc electrodeposits. The electrodeposited zinc electrodes are then fabricated into alkaline zinc-air microbattery measuring 1 cm2 area x ca. 305 µm thick. The use of inorganic MCM-41 membrane separator enables the fabrication of a compact cell design. The quality of the electrodeposited zinc electrodes is gauged directly from the electrochemical performance of zinc-air cell. Zinc electrodeposits prepared from electrolytic bath of 2 M NH4Cl produces the highest discharge capacity.ABSTRAK: Elektrod zink dengan kadar discas tinggi telah dihasilkan dengan proses saduran elektrokimia. Takungan elektrolit terdiri daripada zink klorida sebagai sumber logam dan ammonium klorida sebagai elektrolit sokongan. Kepekatan elektrolit sokongan diubah daripada sifar hingga 4 M, sementara kepekatan zink klorida ditetapkan pada 2 M. Ini bertujuan untuk mendapatkan saduran zink yang poros dengan luas permukaan per unit isipadu dan sentuhan antaramuka yang dipertingkatkan. Ciri-ciri ini akan menyumbang terhadap pengurangan kehilangan disebabkan kerintangan, pertambahan dalam gunapakai bahan aktif dan akhirnya menghasilkan sel elektrokimia berprestasi tinggi. Physisorpsi nitrogen pada 77 K telah digunakan untuk mengukur luas permukaan BET dan isipadu liang saduran zink. Saduran zink kemudiannya dijadikan elektrod bagi bateri mikro zink-udara beralkali dengan saiz 1 cm2 luas x ca. 305 µm tebal. Penggunaan membran tak organik MCM-41 membolehkan pembuatan sel dengan rekabentuk padat. Kualiti elektrod saduran zink telah dinilai secara lansung daraipada prestasi elektrokimia sel zink-udara. Saduran zink yang disediakan daripada takungan elektrolit 2 M NH4Cl menghasilkan kapasiti discas tertinggi.KEY WORDS (keyword)): Zinc electrodeposition, High discharge rate electrode, MCM-41 separator, Zinc-air cell and Alkaline microbattery.
