The Rohm of the battery increases following vibration at various frequencies. This phenomenon may be attributed to the collision and deformation of the collector during the vibration process . It is noteworthy that the SEI film impedance and charge transfer impedance of the battery decrease after vibration.
The impedance of the vibrating battery at each stage after cycling is notably higher than that of the fresh battery subjected to direct cycling. This observation suggests that the vibration process has a substantial impact on the internal structure of the battery.
This study investigates the alterations in the electrochemical performance of batteries subjected to vibration at different frequencies and the changes in cyclic batteries after vibration. The degradation mechanism of the battery during vibration and cycling is revealed through electrochemical characterization and post-mortem analysis.
The peak drop and offset indicate that vibration exacerbates the loss of active lithium and active materials in the battery during cycling. Vibration induces a discernible darkening in the surface color of the battery separator proximal to the mandrel, concomitant with the breaking of active particles on the cathode surface.
The vibration encountered by batteries during transportation, as well as electric vehicle batteries, modules, and battery packs, is typically generated by demanding road conditions and the internal structure of the vehicle.
