“…[17] At the same time, new electrode and electrolyte materials are being tested with the goal of achieving enhanced conversion kinetics and better discharge capacities. [18,19] The first environmental assessment for the Mg-S battery, to the best of the authors' knowledge, was conducted by Montenegro et al (2019) [13] based on the first pouch-cell prototype for this type of battery. [12] The authors used the life cycle assessment (LCA) methodology to evaluate the potential environmental impacts of the battery manufacture stage, also called cradle-to-gate analysis.…”

Energy‐storage systems are considered as a key technology for energy and mobility transition. Because traditional batteries have many drawbacks, there are tremendous efforts to develop so‐called postlithium systems. The magnesium–sulfur (MgS) battery emerges as one alternative. Previous studies of Mg–S batteries have addressed the environmental footprint of its production. However, the potential impacts of the use‐phase are not considered yet, due to its premature stage of development. Herein, a first prospective look at the potential environmental performance of a theoretical Mg–S battery for different use‐phase applications is given to fill this gap. By means of the life cycle assessment (LCA) methodology, an analysis of different scenarios and a comparison with other well‐established technologies are conducted. The results suggest that the environmental footprint of the Mg–S is comparable with that of the commercially available counterparts and potentially outperforms them in several impact categories. However, this can only be achieved if a series of technical challenges are first overcome.

“…Table 1 presents some Mg-S batteries utilizing separator materials such as PTFE [25], PE film [21], borosilicate glass fiber sheet [71,90], glass fiber [22,26,28,30,52,67,68,72,74], Celgard microporous membrane [13,30,93], CNF-coated glass fiber [24], glass microfiber filter [70,73], ENTEK PE membrane [94], glass wool [98], and others. It is seen that the glass fiber separator is the most often used in Mg-S batteries.…”

Nowadays, rechargeable batteries utilizing an S cathode together with an Mg anode are under substantial interest and development. The review is made from the point of view of materials engaged during the development of the Mg–S batteries, their sulfur cathodes, magnesium anodes, electrolyte systems, current collectors, and separators. Simultaneously, various hazards related to the use of such materials are discussed. It was found that the most numerous groups of hazards are posed by the material groups of cathodes and electrolytes. Such hazards vary widely in type and degree of danger and are related to human bodies, aquatic life, flammability of materials, or the release of flammable or toxic gases by the latter.

“…The cathode is coated on a carbon-coated Al foil with a thickness of 18 μm. The reasons why carbon-coated Al foil is used as cathode current collector instead of Cu foil are as follows: (1) Cu current collector could react with S to form copper sulfides, 36,107,108 while carbon-coated Al foil is compatible with S; (2) electrochemical oxidation stability of 0.5 M OMBB electrolyte is 3 V vs Mg/Mg 2+ measured by linear sweep voltammograms, which indicates a relatively high oxidation stability of electrolyte on Al foil; (3) carboncoated on two sides of Al foil can protect the Al foil from corrosion of Cl − in the electrolyte; and (4) the carbon on Al foil can improve adhesion to electrode material, thus achieving a higher S loading. The separator is Celgard 2500 with a thickness of 25 μm.…”

Amid burgeoning environmental concerns, electrochemical energy storage has rapidly gained momentum. Among the contenders in the "beyond lithium" energy storage arena, the magnesium-sulfur (Mg/S) battery has emerged as particularly promising, owing to its high theoretical energy density. However, the gap between fundamental research and practical application is still hindering the commercialization of Mg/S batteries. Here, through reviewing the recent developments of Mg/S batteries technologies, especially with respect to energy density and cost, we present the primary technical challenges on both materials and device level to surpass the energy density and cost-effectiveness of lithium-ion battery. While the high electrolyte-sulfur ratio and the expensive liquid electrolyte are significantly limiting the practical application of Mg/S batteries, we found that solid-state Mg electrolyte appears to be a feasible solution on the basis of energy density and cost evaluation.
