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

摘要

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.
