Choi et al. 40 have investigated the electrochemical performances of Al metal as a negative electrode material with both native and very thin aluminum oxide (Al 2 O 3) layers.
Rechargeable aluminum batteries with aluminum metal as a negative electrode have attracted wide attention due to the aluminum abundance, its high theoretical capacity and stability under ambient conditions.
And we use aluminum (Al) material for the positive electrode of the battery. Using nickel (Ni) material for the negative electrode. And nickel-plated copper (Ni-Cu) material is also available for the negative electrode. There are two parts that make up them. The film and the metal strip.
In search of new non-carbonaceous anode materials for lithium ion batteries, aluminum has been tested as a possible candidate. In order to examine the intrinsic properties of this metal versus a lithium electrode at 293 K, aluminum thin films have been deposited by thermal evaporation and characterized.
The thinnest samples are the less damaged after the electrochemical tests. Despite a huge loss in capacity due to volume changes in the electrode upon cycling, aluminum appears as a good material as a negative electrode for lithium ion batteries. 1. Introduction
However, the aluminum thin films have shown capacities close to 1000 mAh/g. This suggests that aluminum can be a possible candidate as a negative electrode for Li ion cells if an adequate matrix is determined in order to optimize the stability upon cycling and to decrease the capacity fade.
