When a lithium battery is crushed or punctured, the physical trauma can lead to short-circuits within the battery. This damage disrupts the battery’s internal architecture, leading to immediate and intense heat generation. In severe cases, it can cause the battery to rupture and explode.
To reduce the risk in the crushing process of used lithium batteries, 10 used lithium batteries (weighing approximately 1 kg) were first immersed in a NaCl solution with a mass fraction of 20 % and fully discharged for 24 h.
In this paper, the stress wave theory is employed to analyze the dynamic behaviors of 18,650 lithium-ion batteries for the first time. A numerical model of the battery cell is established and validated by experiments, which is then used to study the dynamic response under crushing within a wide scope of crushing velocity (up to 45 m/s).
Lithium-ion battery fires generate intense heat and considerable amounts of gas and smoke. Although the emission of toxic gases can be a larger threat than the heat, the knowledge of such emissions is limited.
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.
Previous studies have been conducted using shredders or hammer crushers to crush waste lithium batteries, but it was found that the use of mechanical crushing would lead to low efficiency of the subsequent separation and extraction of metals and high energy consumption.
