Abstract:
A method for detecting and dosing hydrofluoric acid content of an electrolyte containing lithium hexafluorophosphate LiPF6 in lithium batteries, including measuring a variation in weight of a material that can undergo a surface reaction with the hydrofluoric acid in the electrolyte, the variation being determined by a quartz microbalance.
