However, corrosion has severely plagued the calendar life of lithium batteries. The corrosion in batteries mainly occurs between electrode materials and electrolytes, which results in constant consumption of active materials and electrolytes and finally premature failure of batteries.
The main abuse tests (e.g., overcharge, forced discharge, thermal heating, vibration) and their protocol are detailed. The safety of lithium-ion batteries (LiBs) is a major challenge in the development of large-scale applications of batteries in electric vehicles and energy storage systems.
In this framework, non-destructive inspection methods play a fundamental role in assessing the condition of lithium-ion batteries, allowing for their thorough examination without causing any damage.
In general, the EIS method has apparent positive significance for real-time safety monitoring of LIBs and other batteries. The real and imaginary parts of the impedance can separately establish functional relationships with temperature and be used to accurately monitor the working state of the battery.
