Mechanically induced internal failure of lithium-ion batteries were examined. Multiple individual parameters of internal short circuit were investigated on batteries. SOC had a significant influence on battery behavior after the internal short circuit was triggered. Thickness and material of electrodes had little effect on battery mass loss rates.
