Used primarily as a high-performance electrolyte additive in lithium-ion batteries, it enhances the stability and efficiency of the battery by improving the solid electrolyte interface (SEI) layer. This leads to increased cycle life and safety of the battery. Additionally, it is employed in organic synthesis as a strong acid catalyst, facilitating various chemical reactions, including esterifications and condensations. Its unique properties also make it suitable for use in specialty chemicals and advanced materials, where its thermal and chemical stability are highly valued.
