Failure Analyses of Cylindrical Lithium-Ion Batteries Under
In this paper, a detailed model of the cylindrical lithium-ion battery is established, which not only establishes the anode, cathode, separator, winding, and battery casing but also assigns
The storage and transportation of lithium-ion batteries under reduced ambient pressure have critical safety concerns. This work develops a model to simulate and understand the thermal runaway of a cylindrical battery cell at different sub-atmospheric pressures.
To describe the mechanical response of cylindrical batteries more comprehensively, Zhu et al. established a detailed model of cylindrical lithium-ion batteries, which can only reveal the failure sequence of components under axial compression. Additionally, some detailed models have taken into account the effects of strain rate [17, 18].
Through the indentation experiment and simulation of the battery cell, it can be found that K-type localized shearing failure occurs inside the battery cell due to the presence of the winding, which is the unique fracture mode of the cylindrical lithium-ion batteries.
The lithium metal-based solid-state batteries (LMSBs), which is regarded as the next generation energy storage devices, is also introduced as the electrochemical-mechanical coupled effects are more prominent. To better achieve the ambitious goal of this review, it is necessary to clarify our scope.
