Hydrofluoric acid (HF) titration provides insights into electrolyte decomposition and impurity levels.

Hydrofluoric acid (HF) is a critical quality control parameter found in battery electrolytes that will significantly impact cell stability, performance, and safety. HF titration provides insights into electrolyte decomposition and impurity levels. This application note highlights the importance of HF measurements in maintaining electrolyte quality.

High levels of HF are detrimental as it can corrode battery components, degrade the solid electrolyte interphase (SEI) layer, and ultimately compromise overall battery lifespan. Quantifying HF provides insight into the extent of LiPF₆ degradation therefore routine HF monitoring is essential for quality assurance and safe battery manufacturing.
