Why are aluminum batteries considered compelling electrochemical energy storage systems?
Aluminum batteries are considered compelling electrochemical energy storage systems because of the natural abundance of aluminum, the high charge storage capacity of aluminum of 2980 mA h g−1/8046 mA h cm−3, and the sufficiently low redox potential of Al3+/Al. Several electrochemical storage technologies based on aluminum have been proposed so far.
What is an aluminum battery?
In some instances, the entire battery system is colloquially referred to as an “aluminum battery,” even when aluminum is not directly involved in the charge transfer process. For example, Zhang and colleagues introduced a dual-ion battery that featured an aluminum anode and a graphite cathode.
Which electrochemical storage technologies are based on aluminum?
Several electrochemical storage technologies based on aluminum have been proposed so far. This review classifies the types of reported Al-batteries into two main groups: aqueous (Al-ion, and Al-air) and non-aqueous (aluminum graphite dual-ion, Al-organic dual-ion, Al-ion, and Al-sulfur).
What is a fiber-shaped aluminum-air battery?
Recently, an all-solid-state fiber-shaped aluminum-air battery with an electrode composed of cross-stacked aligned carbon-nanotube/silver-nanoparticle sheets with a specific energy of 1,168 Wh/kg was described (Xu et al., 2016).
What is a rechargeable aluminum ion battery?
An aluminum/chlorine rechargeable cell employing a room temperature molten salt electrolyte. J. Electrochem. Soc. 135, 650–654 (1988). Jayaprakash, N., Das, S. & Archer, L. The rechargeable aluminum-ion battery.
What are the disadvantages of aluminum batteries based on aqueous or protic systems?
Despite its low cost, simple operation, and reduced environmental impact, aluminum batteries based on aqueous or protic systems exhibit fatal drawbacks, such as the passivating oxide film formation decreasing the battery voltage and efficiency, hydrogen side reactions, and material corrosion.
