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.
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. However, the understanding of sidewall rupture in high specific energy cells under mechanical abuse conditions remains limited.
See all authors As the energy density of lithium-ion cells and batteries increases, controlling the outcomes of thermal runaway becomes more challenging. If the high rate of gas generation during thermal runaway is not adequately vented, commercial cell designs can rupture and explode, presenting serious safety concerns.
Lithium-ion batteries (LIBs) are crucial components for electric vehicles (EVs), and their mechanical and structural stabilities are of paramount importance. In this study, the mechanical properties of an aluminum-laminated pouch sheet, as a key component of pouch-type LIBs, are examined.
In this study, the rupture of both 20700 and 18650 batteries was caused by blockage of the battery vent region. This prevented the release of the generated gas.
The findings from this study can contribute to assessing the risk associated with different triggers for thermal runaway. Lithium-ion cells have been widely used in electric vehicles (EVs) due to their high energy density, 1,2 free emission, low self-discharge, and low memory effect.
