“…So far, only a few types of conventional intercalation materials have been identified that are capable of storing Mg 2+ ions reversibly. [8][9][10][11][12][13][14][15] Thus, the challenges to realize the rechargeable Mg battery technology are not only the improvement of the electrolyte toward high oxidative stability, but also the discovery of cathode materials enabling high performance of Mg batteries.…”

Rechargeable magnesium (Mg) battery has been considered as a promising candidate for future battery generations because of its potential high-energy density, its safety features and low cost. The challenges lying ahead for the realization of Mg battery in general are to develop proper electrolytes fulfilling a multitude of requirements and to discover cathode materials enabling high-energy Mg batteries. The combination of Mg anode with a sulfur cathode is one of the promising electrochemical couples due to its advantages of safety, low costs, and a high theoretical energy density of over 3200 Wh/L. However, the research on magnesium-sulfur (Mg-S) battery is just at its beginning and the development of suitable electrolytes has been the key challenge for further improvement, and, thus, in the focus of recent research. In this review, we highlight the recent progress achieved in Mg electrolytes and Mg-S batteries and discuss the major technical issues, which must be resolved for the improvement of Mg-S batteries.

“…[115,116] For these reasons, since the Mg rechargeable cell was proposed by Gregory et al [117] and the first prototype of a Mg ion cell was reported by Aurbach et al, [118] most research on Mg rechargeable cells has mainly focused on developing high capacity cathodes and appropriate organic electrolytes, which are strongly emphasized in the recent review articles. [115,116,119] In the historical development of Mg rechargeable cells, there were two significant breakthroughs; [116] (1) the report of solutions containing Mg organo-borate moieties that provide an environment for reversible Mg deposition/dissolution, even in the absence of highly reducing Grignard reagents, (2) (copyright is needed) [116] Since the DCC family of electrolytes was proposed, many types of cathodes have been tested such as transition metal disulfides [120] and Cheveral type cathodes in the DCC electrolytes. [118] could be achieved due to the fast insertion kinetics of Mg 2+ ions provided by its structure that has many vacant sites for Mg, a short diffusion distance between accommodation sites and easy charge compensation of the metallic Mo cluster during Mg diffusion.…”

Light metals have been widely used as electrode materials for batteries owing to their low standard redox potential, their low equivalent weight, large specific capacity, and great abundance. Both primary and secondary cells including light metals as electrode material have influenced all aspects of our lives, e.g., electrically operated toys, power tools, and portable electronics such as cell phones, smart pads, and laptop computers. Among all battery systems, rechargeable lithium (Li) ion cells have been used most widely in recent years owing to their high specific power, high energy density, and ambient temperature operation. However, Li‐ion cells are facing difficult challenges in satisfying the emerging market for advanced applications demanding high‐performance rechargeable batteries for applications such as electric vehicles, high‐performance portable electronics, and large‐scale electrical energy storage systems. Unfortunately, current Li‐ion cells cannot satisfy demands such as low cost, much improved safety, larger energy density, faster charge/discharge rates, and longer service life, so intensive effort is necessary to develop the next generation of cells. In this article, the limitations of current Li‐ion cells and various advanced materials for each component of the Li‐ion cell, in addition to other promising candidates for cells beyond Li ion, such as the Li/S cell and Na‐ and Mg‐based rechargeable cells, and metal/air cells are discussed.

“…[1,2] Besides, Mg metal possesses huge intrinsic advantages, including high safety (non-dendrite formation and less reactiveness at ambient atmosphere) and low cost benefitted from its natural abundance. [1][2][3] Unfortunately, the research of Mg batteries has received comparatively less attention owing to the absence of high-performance cathodes together with comprehensively well-performed Mg-ion electrolytes.…”

“…[4] It delivers a limited specific capacity ≈100 mAh g −1 and a relatively low operation voltage of ≈1.1 V versus Mg, making this Mg battery system energetically uncompetitive. [2,5] The conversion-type sulfur (S) and selenium (Se) cathodes, with theoretical volumetric capacity of 3467 mAh cm −3 for S and 3268 mAh cm −3 for Se, fulfill the criteria of high energy density, high safety, materials sustainability, and cost-effective features. [6][7][8] Nevertheless, researches on rechargeable Mg/S and Mg/Se battery systems are still in the nascent stage.…”
