METHOD FOR DETECTING AND DOSING HYDROFLUORIC ACID IN AN ELECTROLYTE CONTAINING LITHIUM HEXAFLUOROPHOSPHATE LIPF6 FOR LITHIUM BATTERIES

摘要

The invention relates to a method for detecting and dosing the hydrofluoric acid content of an electrolyte containing lithium hexafluorophosphate LiPF6 in lithium batteries, implemented by measuring the variation in weight of a material that can undergo a surface reaction with the hydrofluoric acid in the electrolyte, said variation being determined by means of a quartz microbalance.
