Rechargeable aluminum batteries with aluminum metal as a negative electrode have attracted wide attention due to the aluminum abundance, its high theoretical capacity and stability under ambient conditions.
Positive electrode materials for non-aqueous aluminium batteries Positive electrodes for non-aqueous aluminium batteries can be divided into two categories: those that store chloroaluminate species, which have been shown to have high performance, and those that store aluminium, which have not.
Sulphur has also been attempted as a positive electrode for aluminium batteries due to its theoretical specific energy (based on total electrode mass) of 1340 Wh kg −1 based on a discharge potential of 1.1–1.25 V vs. Al|Al (III) – significantly higher than current lithium-ion batteries [ 116 ].
Entirely new DES with improved performance need to be discovered for them to gain relevance in non-aqueous aluminium batteries. Graphite-based positive electrodes offer the best overall performance due to the stability and high average discharge potential.
Metal negative electrodes that alloy with lithium have high theoretical charge storage capacity and are ideal candidates for developing high-energy rechargeable batteries. However, such electrode materials show limited reversibility in Li-ion batteries with standard non-aqueous liquid electrolyte solutions.
