Lithium hexafluoroarsenate(V) is primarily used as an electrolyte in advanced lithium-ion batteries. Its high ionic conductivity and stability at elevated temperatures make it suitable for applications requiring high energy density and long battery life. It is often employed in specialized batteries for electric vehicles, aerospace systems, and portable electronics where performance and safety are critical. Additionally, its use in research and development of next-generation battery technologies highlights its importance in improving energy storage solutions. However, due to the presence of arsenic, handling and disposal require strict safety protocols to minimize environmental and health risks.
