CC-BY 4.0. Magnesium (Mg) metal batteries exhibit great potential as energy storage systems beyond lithium, owing to their inherent safety, material sustainability, and low cost. However, their development is hindered by the lack of a suitable electrolyte enabling a reversible Mg deposition and dissolution.
Based on the comparably low potential of sulfur reduction and Li 2 S oxidation (≈2.2 V vs. Li|Li + ), however, sulfur-based electrodes can also be considered as the negative electrode in combination with a high-potential positive electrode.
Since the design principles of cathode materials for Mg–S batteries are at least similar to those of Li–S batteries in terms of high sulfur loading, high conductivity and good surface chemisorptivity, polymers containing covalently bound sulfur as cathode material might present a future research direction.
