Used primarily as an electrolyte salt in lithium-ion batteries, enabling efficient ion transport between electrodes. Its high solubility in organic solvents and good thermal stability make it suitable for battery applications where performance and safety are critical. Also employed in electrochemical cells and as a source of fluoride ions in certain chemical syntheses. Due to its ability to dissociate readily, it supports high conductivity in non-aqueous electrolyte systems. Handling requires care, as it can decompose to release toxic hydrogen fluoride upon contact with moisture.
