Vibration Experiment for Lithium Battery

The vibration test method for lithium battery :

After the battery is discharged to 3.0V at 0.2C, it is charged to 4.2V with constant current and constant voltage at 1C, and cut-off current of 10mA. After being left for 24 hours, it will vibrate under the following conditions:

The vibration experiment is carried out with the vibration frequency from 10 Hz to 60 Hz to 10 Hz in 5 minutes with amplitude of 0.06 inches. The battery vibrates in three axis directions, and each axis vibrates for half an hour.

The battery voltage change should be within ±0.02V, and the internal resistance change should be within ±5mΩ.
