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.
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.

The idea of making batteries with aluminum isn't new. Researchers investigated its potential in the 1970s, but it didn't work well. 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.
The research team knew that aluminum would have energy, cost, and manufacturing benefits when used as a material in the battery's anode -- the negatively charged side of the battery that stores lithium to create energy -- but pure aluminum foils were failing rapidly when tested in batteries. The team decided to take a different approach.
Aluminum, while not typically used as an anode material, is a key player in lithium-ion batteries. It serves as the current collector in the cathode and for other parts of the battery.
