“…In contrast to Li or Na, Mg as a metallic anode has the nature of dendrite-free deposition. [6,7] Moreover, Mg has a reduction potential of −2.4 V versus SHE and can be safely handled in air. An important aspect of cost and sustainability is the high abundance of Mg element in the earth crust and its ready availability in various minerals all over the globe, e.g., as dolomite (CaCO 3 ·MgCO 3 ) or as magnesite (MgCO 3 ).…”

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.

The electrochemical behavior of magnesium deposition-dissolution on scratched aluminum foils in Grignard reagent/tetrahydrofuran (THF) solutions (1 mol L 1 EtMgBr/THF), which is regarded as a potential electrolyte of rechargeable magnesium batteries, was studied by using various methods such as cyclic voltammetry (CV), scanning electron microscopy (SEM), X-ray diffraction (XRD) and charge-discharge (deposition-dissolution) tests. The results present that the obtained magnesium deposits do not exhibit the morphology of dendrite and the Mg-Al alloy is not found on the surface of aluminum foils. The magnesium deposited on the aluminum substrates have excellent electrochemical cyclic performance in 1 mol L 1 EtMgBr/THF solution. The aluminum can be used as a candidate material of the negative current collector for rechargeable magnesium batteries. Electrochemical energy storage devices are key components for innovative power train systems such as plug-in hybrid vehicle (PHV), fuel cell hybrid vehicle (FCHV), and electric vehicle (EV) [1,2]. Currently, Li-ion batteries have been widely used in the fields of hybrid electric vehicles (HEV) and EV due to their high energy densities. However, there are some shortcomings which have not been resolved in Li-ion batteries, such as poor safety performance and high cost [3,4]. Magnesium as an electrode has the advantages of high Faradic capacity, environmental acceptability, good reliability, high safety and low cost. Therefore, the rechargeable magnesium battery is considered as an ideal substitution for the Li-ion battery in the future [5,6], which is becoming an attractive power battery and developed by many international companies and research institutes [7,8]. Liebenow [9] has investigated that the reversibility of electrochemical magnesium deposition on Au and Ag substrates in Grignard reagent/ether solutions. The magnesium deposits on Au and Ag substrates have smooth and compact morphologies. Aurbach et al. [10][11][12][13][14] studied the electrochemical deposition-dissolution mechanisms of magnesium on Au substrates in different ethereal solutions of complexes of the Mg(AX 4n R n′ R′ n″ ) 2 type (A=Al, B; X=Cl, Br; R, R′= alkyl or aryl groups; and n′+n″=n) by using various analytical techniques. They found that the electrolyte was a key factor on morphologies of the magnesium deposits. Nuli et al. [15,16] reported that electrochemical deposition-dissolution processes of magnesium in both ionic liquid electrolytic solutions of BMIMBF 4 and PP13TFSI with 1 mol L 1 Mg(CF 3 SO 3 ) 2 are highly reversible. Wang et al. [17] have studied the electrochemical magnesium deposition-dissolution behavior in a mixed ionic liquid of BMIMBF 4 and PP13TFSI with the volume ratios of 2 : 1, 3 : 1, and 4 : 1 in the presence of 0.3 mol L 1 Mg(CF 3 SO 3 ), respectively. They found that those mixed electrolyte systems were well compatible with the deposition-dissolution of magnesium
