The team observed that the aluminum anode could store more lithium than conventional anode materials, and therefore more energy. In the end, they had created high energy density batteries that could potentially outperform lithium-ion batteries.
Aluminum-ion batteries (AIB) AlB represent a promising class of electrochemical energy storage systems, sharing similarities with other battery types in their fundamental structure. Like conventional batteries, Al-ion batteries comprise three essential components: the anode, electrolyte, and cathode.
It surpasses lithium by a factor of four and sodium by a factor of seven, potentially resulting in significantly enhanced energy density. These batteries, now commonly referred to as aluminum-ion batteries, offer numerous advantages.
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.
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.
Rechargeable lithium-ion (Li-ion) batteries, surpassing lead-acid batteries in numerous aspects including energy density, cycle lifespan, and maintenance requirements, have played a pivotal role in revolutionizing the field of electrochemical energy storage [, , ].
