A triangle of factors affecting sidewall rupture of lithium-ion batteries was proposed. X-ray computed tomography of internal structure of cells after thermal runaway. Sidewall rupture of lithium-ion batteries plays an important role in thermal runaway (TR) propagation because flame burst from the side of cell can directly heat adjacent cells.
A lithium ion battery failure is initiated by a certain type of abuse, whether it be electrical, thermal, or mechanical abuse. This stage of a failure is normally detectable by a battery management system, which is constantly monitoring the physical characteristics of the individual lithium ion batteries.
Since the cell rupture time tr and charging electric energy decreased with increasing C-rate, the electric energy was considered to be a driver for the thermal runaway of batteries and contributed to the onset of cell rupture by providing activation energy, which refers to the excess energy accumulated inside to initiate the battery failure.
Lithium battery fires typically result from manufacturing defects, overcharging, physical damage, or improper usage. These factors can lead to thermal runaway, causing rapid overheating and potential explosions if not managed properly.
In severe cases, it can cause the battery to rupture and explode. Bending a lithium battery or subjecting it to a strong impact can cause internal deformation. This deformation can lead to mechanical failure of the battery’s components and create conditions ripe for thermal runaway, where the battery heats uncontrollably.
Different form factors lend to different reasons why this happen. For example, cylindrical cells generate off-gassing compounds because of a vent feature of the lithium ion battery cell. In pouch cells, there is a rupture in the seal which leads to an off-gassing event. This stage of failure is detectable by the Li-ion Tamer ® off-gas monitor.
