Abstract
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.
Highlights
Nowadays, it is observed the strong development of various reversible electrical energy storages based on Li electrodes, which are applied in commonly utilized electronic devices, automotive control and drive systems, and net applications [1,2,3,4,5]
Two sets of twenty hazards identified belonged to the hazard groups related to the toxic or allergic effects on the eyes and respiratory tract, respectively
Two single hazards identified belonged to the hazard groups related to the generation of genetic defects and cancers, respectively
Summary
It is observed the strong development of various reversible electrical energy storages (batteries) based on Li electrodes, which are applied in commonly utilized electronic devices, automotive control and drive systems, and net applications [1,2,3,4,5]. Parambath et al [17] noticed that Mg–S cells have a high overpotential between charge/discharge cycles, rapid capacity fading, low cycling efficiency, and slow kinetics Such problems are strongly affected by the dissolution of polysulfides (PSs) in the electrolyte and their subsequent shuttling to the Mg anode side. Montenegro et al [35] described a prototype magnesium rechargeable battery (MRB) of the Mg–S-type comprising cells, each with an Mg foil anode, an S cathode, a magnesium tetrakis (hexafluoroisopropyloxy) borate electrolyte, a plastic separator, and Al composite pouch cell packaging. They found that the pouch cell housing and electricity requirements for battery manufacture posed potential threats to the environment. According to [76,77], it is self-heating and may catch fire
