This work uses the electrochemical impedance spectroscopy to study how the battery impedance changes with aging. Tests performed with a fresh cell and another one aged at different states of charge and temperature were compared. The obtained results can be useful to determine the best possible use for a second life of the battery.
Lithium ion battery (LIB) degradation originates from complex mechanisms, usually interacting simultaneously, and in various degrees of intensity. Due to its complexity, to date, identifying battery aging mechanisms remains challenging. To resolve such issue, various techniques have been developed, including in-situ incremental capacity (IC) and peak area(More)
