Are aqueous aluminum batteries a promising post-lithium battery technology?

Nature Communications 13, Article number: 576 (2022) Cite this article Aqueous aluminum batteries are promising post-lithium battery technologies for large-scale energy storage applications because of the raw materials abundance, low costs, safety and high theoretical capacity.

Are aqueous aluminum ion batteries good for energy storage?

This green electrolyte for high-energy AAIBs holds promises for large-scale energy storage applications. Aqueous aluminum ion batteries (AAIBs) have received growing attention because of their low cost, safe operation, eco-friendliness, and high theoretical capacity.

Are aluminum batteries a good alternative to lithium ion batteries?

Aluminum batteries (ABs) as alternative of lithium and sodium ion batteries. ABs fulfill the requirement for a low-cost and high-performance energy storage system. Surface engineering suppresses the corrosion of aluminum anode. Optimization of suitable electrolyte, separator, and cathode materials.

Is Al a potential electrode material for batteries?

Al has been considered as a potential electrode material for batteries since 1850s when Hulot introduced a cell comprising a Zn/Hg anode, dilute H 2 SO 4 as the electrolyte (Zn/H 2 SO 4 /Al battery), and Al cathode.

Is Al metal a good anode material for post lithium batteries?

Al metal is one of the most attractive anode materials in post-lithium batteries in view of its numerous merits, such as low cost and high Earth abundance, as well as high charge density and gravimetric/volumetric capacities, compared with Na, K, and Zn (Fig. 1a and Supplementary Table 1) 10, 21, 24, 25.

Can aluminum batteries be used as rechargeable energy storage?

Secondly, the potential of aluminum (Al) batteries as rechargeable energy storage is underscored by their notable volumetric capacity attributed to its high density (2.7 g cm −3 at 25 °C) and its capacity to exchange three electrons, surpasses that of Li, Na, K, Mg, Ca, and Zn.
