“…However, Al‐ion batteries suffer from several major issues such as dendrite formation, lack of corresponding cathodes, and being nonrechargeable. [ 11–14 ] Apart from dendritic issue, high charge density of Mg, formation of a passivating interfacial layer, and limitation in the choice of cathode and electrolyte have limited application of Mg. [ 15–18 ] Zinc‐metal batteries (ZMBs) are another potential alternative to Li batteries due to numerous benefits such as high energy density (820 mAh g −1 ), less reactivity, multielectron redox capacity allowing for compatibility with aqueous electrolytes, environmental benignity, stability, low equilibrium potential (−0.76 V vs SHE), safety, high abundance, and low cost. [ 19–25 ] As such, ZMBs are considered as a promising candidate for high capacity systems such as grid storage, where aqueous electrolyte‐based systems are widely used.…”

As one of the most promising energy storage technologies, zinc (Zn)‐metal batteries (ZMBs) have attracted significant attention due to outstanding properties of Zn, including high energy density (820 mAh g−1/5855 mAh cm−3), abundance, low cost, low reactivity, multielectron redox capacity, compatibility with aqueous electrolytes, low equilibrium potential (−0.76 V vs SHE), stability, safety, and environmental benignity. Yet, the existence of some major issues such as surface‐originated parasitic reactions (e.g., corrosion and H2 evolution), formation of dead Zn, and oxide passivation leading to capacity loss in ZMBs are hindering their full potential applications. Addressing these challenges requires profound understanding of mechanism of Zn dendrites formation. Therefore, the aim of the current study is to assess some of the latest challenges and advancements concerning ZMBs, with an emphasis on origin and growth mechanism of Zn dendrites. Herein, it is demonstrated that the Zn electrodeposition does not follow a simple reaction/diffusion limited behavior, and other parameters such as surface energy and surface diffusion barrier play great roles on the morphology and microstructure of the deposited Zn. In addition, recent advances to mitigate Zn dendrite issues by applying modifications on the design of electrode, electrolyte, separator and interface are discussed.

“…Li 36 conducted a comprehensive review of the development of rechargeable MAFC (Figure 4). Primary Mg‐air cells have been investigated since the late 50s and still undergoing progressive evolution starting with the rechargeable Mg2Ni‐air battery to secondary rechargeable MAFC using organic electrolytes 30,37‐39 . However, other metal‐air fuel cells especially Li‐air fuel cell are making huge progress and advancement in development of flexible energy storage system design following the trending revolution in flexible electronic 40‐43 where MAFC are still left behind.…”

“…To better accommodate active catalysts, Li 36 suggested the development of a novel hybrid electrolyte system that comprises the use of a separate non‐aqueous solution for highly active micro/nanoscale Mg and an aqueous solution on the cathode component to curb the formation of the insulating MgO and MgO 2 layer. However, only an in‐depth review of electrolytes for secondary magnesium battery has been established 39 …”

Summary This study aimed to provide a critical review of the magnesium‐air fuel cell (MAFC) system to provide readers with an overall comprehension of MAFC, which focuses on the modification of the magnesium anode and properties of saltwater as an electrolyte. Although MAFC is benign to the environment, it is well‐known for its challenging corrosion issue and by‐product deposition that affect its durability for commercialization and long‐term application. Since that MAFC is able to use seawater as electrolyte, it has great potential to be used as an alternative energy option for the marine sector. This journal will dissect the ability of MAFC to be used as a competitive alternative energy. Over the years, researchers have adopted several approaches, such as experimenting with different types of magnesium alloy and anode fabrication techniques, to tackle corrosion problems to alter the microstructure and mechanical properties of the anode in addition to applying a coating protection and using Mg‐based composite material. Furthermore, studies intriguingly and gradually focused on electrolyte formulation with different types of additives to address the debilitating precipitation issue and improve the discharge performance. Given the problems that arise in the system, currently, MAFC commercial products are only suitable as emergency back‐up power. In future work, an improved storage system for MAFC should be built to accommodate the precipitation products while maintaining the desired cell performance.

“…One of the most interesting solutions seems to be represented by the rechargeable magnesium-ion batteries (MIBs) [ 92 , 93 , 94 , 95 , 96 ], which utilize magnesium cations as the active charge transporting species in solution and (in many cases) metallic magnesium as the anode. A primary advantage of this technology is given by the solid magnesium anode that leads to high energy density values, well above those of lithium-based cells [ 97 , 98 , 99 , 100 , 101 ]. However, some issues have emerged when using elemental magnesium and novel solutions have been proposed.…”

An Overview on Anodes for Magnesium Batteries: Challenges towards a Promising Storage Solution for Renewables

et al. 2021

View full text Add to dashboard Cite

Magnesium-based batteries represent one of the successfully emerging electrochemical energy storage chemistries, mainly due to the high theoretical volumetric capacity of metallic magnesium (i.e., 3833 mAh cm−3 vs. 2046 mAh cm−3 for lithium), its low reduction potential (−2.37 V vs. SHE), abundance in the Earth’s crust (104 times higher than that of lithium) and dendrite-free behaviour when used as an anode during cycling. However, Mg deposition and dissolution processes in polar organic electrolytes lead to the formation of a passivation film bearing an insulating effect towards Mg2+ ions. Several strategies to overcome this drawback have been recently proposed, keeping as a main goal that of reducing the formation of such passivation layers and improving the magnesium-related kinetics. This manuscript offers a literature analysis on this topic, starting with a rapid overview on magnesium batteries as a feasible strategy for storing electricity coming from renewables, and then addressing the most relevant outcomes in the field of anodic materials (i.e., metallic magnesium, bismuth-, titanium- and tin-based electrodes, biphasic alloys, nanostructured metal oxides, boron clusters, graphene-based electrodes, etc.).
