The key to this advancement lies in a new electrode material—an organic redox polymer based on phenothiazine. This innovative material allows aluminum-ion batteries to achieve a storage capacity of 167 mAh per gram, surpassing the graphite commonly used in lithium-ion batteries.
“It’s interesting that we can use aluminum as a battery material, because it’s cost-effective, highly recyclable, and easy to work with.” The idea of making batteries with aluminum isn’t new. Researchers investigated its potential in the 1970s, but it didn’t work well.
So the MIT team set out to design a new type of battery out of readily available, inexpensive materials. After a search and some trial and error, they settled on aluminum for one electrode and sulfur for the other, topped off with an electrolyte of molten chloro-aluminate salt.
When used in a conventional lithium-ion battery, aluminum fractures and fails within a few charge-discharge cycles, due to expansion and contraction as lithium travels in and out of the material. Developers concluded that aluminum wasn’t a viable battery material, and the idea was largely abandoned.
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.
The study was conducted by a team of researchers from Flinders University in South Australia and Zhejiang Sci-Tech University in China. The new batteries are made using special materials known as stable organic radicals which contain a crucial element 2,2,6,6-tetramethylpiperidyl-1-oxy – also known as TEMPO.
Aluminum, being the Earth's most abundant metal, has come to the forefront as a promising choice for rechargeable batteries due to its impressive volumetric capacity. It surpasses lithium by a factor of four and sodium by a factor of seven, potentially resulting in significantly enhanced energy density.
