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.
Abstract: In this paper, a diagnostic method for identifying an external short circuit (ESC) fault for a lithium-ion battery is developed based upon active characterization experiments and online validation. The proposed method examines three criteria: voltage variation, current variation and temperature change rate.
The accidents cause damage on people and properties, reducing consumers’ confidence in the applications of lithium-ion batteries. The battery failure always occurs with internal short circuit (ISC) , .
External short circuit (ESC) faults pose severe safety risks to lithium-ion battery applications. The ESC process presents electric thermal coupling characteristics and becomes more complex when the batteries operate in large group, which often lead to serious consequences.
