These challenges encompass the intricate Al 3+ intercalation process and the problem of anode corrosion, particularly in aqueous electrolytes. This review aims to explore various aluminum battery technologies, with a primary focus on Al-ion and Al‑sulfur batteries.
Research on corrosion in Al-air batteries has broader implications for lithium-ion batteries (LIBs) with aluminum components. The study of electropositive metals as anodes in rechargeable batteries has seen a recent resurgence and is driven by the increasing demand for batteries that offer high energy density and cost-effectiveness.
So far, the publications on Al-S batteries mostly reported ex-situ studies of the Al-ion electrolyte and the sulfur cathode during cycling. After discharge, it has been determined the presence of all possible sulfur species, i.e. elemental sulfur, S 82−, S 62−, S 42−, S 22− and S 2−.
Consequently, any headway in safeguarding aluminum from corrosion not only benefits Al-air batteries but also contributes to the enhanced stability and performance of aluminum components in LIBs. This underscores the broader implications of research in this field for the advancement of energy storage technologies. 5.
