The results indicate that, when a battery is over-charged, the battery’s surface temperature increases first because of ohmic heat, and after that, internal short-circuit occurs, resulting in the battery experiencing thermal runaway. However, in the case of over-discharge, the battery’s surface temperature rise is limited. Therefore, during actual use, attention needs to be paid so as to prevent a battery from over-charge.
