Abstract Among high-capacity materials for the negative electrode of a lithium-ion battery, Sn stands out due to a high theoretical specific capacity of 994 mA h/g and the presence of a low-potential discharge plateau. However, a significant increase in volume during the intercalation of lithium into tin leads to degradation and a serious decrease in capacity. An …
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.
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
Anode side of aqueous batteries is also one of the main bottlenecks for realizing the large-scale application of safe aqueous electrolyte in various industries. The narrow ESW of water induces the side-reactions such as HER, dendrite growth, corrosion, and formation of passivation layer at the anodes.
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.
However aqueous electrolyte-based batteries face challenges, such as the narrow ESW of water (1.23 V) and the decomposition of water at the electrode, making electrode selection difficult. Researchers are working to overcome these challenges to use safe and environmentally friendly water as a solvent. One challenge is HER at the anode side.
The purpose of this work is to investigate a rechargeable Al-ion battery using an aqueous water-in-salt (WIS) electrolyte system focusing on the oxide barrier and corrosion of the Al metal. Al-ion cells were thus constructed with various WIS electrolyte concentrations and investigated using a graphitic cathode.
