METHOD FOR MONITORING A LI-ION BATTERY AND MONITORING DEVICE FOR THE IMPLEMENTATION THEREOF

摘要

The invention relates to a method for monitoring an electrochemical cell or a battery (1), especially a method for monitoring the first charging of an electrochemical cell or a battery (1) of the Li-ion type, comprising a step of acquiring data relating to acoustic emissions produced in the electrochemical cell or in the battery, and, using the acquired data, a step of detecting the formation of a passivation film on an electrode of the electrochemical cell or the battery and/or detecting the first lithium storage on an electrode of the electrochemical cell or the battery.
