The main challenges to implement sustainable energy storage technologies are the utilization of earth-abundant recyclable materials, low costs, safe cell reactions and high performance, all in a single system. Aluminum batteries seem to cover these requirements. However, their practical performance is still not comparable with the state of the art high performance batteries. A key aspect to further development could be the combination of aluminum with charge storage materials like conductive polymers in non-aqueous electrolytes taking advantage of the properties of each material. This review presents the approaches and perspectives for rechargeable aluminum-based batteries as sustainable high-performance energy storage devices. The storage of electricity is a key component in the drive to a sustainable energy society. However, current energy storage devices, like high performance lithium-ion batteries, have constrained raw material resources, difficult recycling process and danger of flammability. Far less attention has been directed to the use lightweight aluminum based batteries in non-aqueous systems as aluminum has lower cost, is more abundant and is safer than lithium. Furthermore, its specific capacity of 2980 mAh g −1 and volumetric capacity of 8040 mAh cm −3 , respectively, are higher than lithium. The number of studies on rechargeable aluminum-based batteries in non-aqueous systems has increased 10-fold in the last decade (Figure 1). Therefore, it seems appropriate and timely to review the state of the art and the implementation of novel ideas and approaches made for rechargeable high performance aluminum-based batteries and reflect on the perspectives, challenges and limitations that these relatively new systems face. Gifford et al. described this novel battery system in 1988 with aluminum and graphite as the negative and positive electrodes respectively, in a Lewis acidic chloroaluminate ionic liquid at room temperature. Chloroaluminate anions intercalated into the graphite electrode reaching 64 Wh kg −1 specific energy at 1.7 V discharge voltage over 150 cycles and 80-90% coulombic efficiency.2 The same idea was taken up several years later by various research groups 1,[3][4][5]

“…Additives such as Li, K and tetrabutylammonium (TBA) salt can be mixed with the electrolyte to help dissolve the oxygen reduction products and increase the discharge capacity of the battery. However, there was no clear indication regarding whether aprotic electrolytes could be used in aluminum-air batteries until it was recently reported that an EMImCl/AlCl 3 acidic solution had been developed as an innovative electrolyte for aluminum-air batteries, exhibiting current densities of up to 0.6 mAcm -2 [91]. In another study by Gelman et al [92], it was reported current densities of up to 1.5 mAcm -2 could be achieved by using EMIm(HF) 2.3 F as the electrolyte.…”

“…A few recent studies, however, have begun to examine secondary room-temperature non-aqueous systems based on other alkali and alkaline-earth metals such as sodium [144][145][146], potassium [147], magnesium [148,149], and aluminum [150], as shown in Table 2. The high abundance of these elements is often provided as a motivation for these systems, although projections indicate that the worldwide supply of Li is adequate for the next century [151].…”

“…The fact that NaO 2 and KO 2 are more stable than LiO 2 has been attributed to the smaller size of the Li + cation [56]. In addition to alkali-metal-based systems, recent studies have recently reported secondary non-aqueous metal-oxygen cells using magnesium [148,149] and aluminum [150] negative electrodes. These chemistries are noteworthy because the theoretical gravimetric and volumetric energy densities of cells that discharges to MgO or Al 2 O 3 surpass the energy densities of a cell that discharges to Li 2 O 2 , Fig.…”

A metal-oxygen battery (sometimes referred to as a 'metal-air' battery) is a cell chemistry in which one of the reactants is gaseous oxygen, O 2 . Oxygen enters the cell typically in the positive electrode-perhaps after being separated from an inflow of air-and dissolves in the electrolyte. The negative electrode is typically a metal monolith or foil. Upon discharge, metal cations present in the electrolyte react with dissolved oxygen and electrons from the electrode to form a metal-oxide or metal-hydroxide discharge product. In some chemistries the discharge product remains dissolved in the electrolyte; in other systems it precipitates out of solution, forming a solid phase that grows in size as discharge proceeds. In secondary metal-oxygen batteries the recharge process proceeds via the decomposition of the discharge phase back to O 2 and dissolved metal cations. In light of the processes associated with discharge and charging, reversible metal-oxygen batteries with solid discharge products are often referred to as precipitation-dissolution systems, a category that also includes lithium-sulfur batteries.The interest in metal-oxygen chemistries follows from their very high theoretical energy densities. Figure 1 summarizes the gravimetric and volumetric energy densities for several metal-oxygen couples, and compares these to the theoretical energy density of a conventional lithium-ion battery. On the basis of these energy densities, it is clear that many metal-oxygen systems hold promise for surpassing the state-of-the-art Li-ion system. Achieving this goal, however, remains a significant challenge when factors beyond energy density are accounted for: cycle life, round-trip efficiency, and cost
