Characterization study on external short circuit for lithium-ion ...
The conditions for failure termination differ between series and series-parallel modules. In a series module, a single battery cell failure is enough to break the short circuit. In contrast, for a series-parallel module, it requires the complete failure of all cells within one parallel branch to disrupt the short circuit. This leads to more ...

Quantification of Lithium Battery Fires in Internal Short Circuit
Single-layer internal shorting in a multilayer battery is widely considered among the "worst-case" failure scenarios leading to thermal runaway and fires. We report a highly reproducible method to quantify the onset of fire/smoke during internal short circuiting (ISC) of lithium-ion batteries (LiBs) and anode-free batteries. We unveil that ...
