Fire Spread due to Thermal Runaway in a Lithium-ion Battery Cell

Poster (konferens), 2014

The risk of spreading of fire between Lithium-ion battery cells is assessed using Finite-Element (FE) modelling of the heat transfer initiated by a thermal runaway. The results are contrasted to experimental data where the heat release rate (HRR) is utilized as an input to the simulation. It is found that the temperature increase in a neighbouring cell can be quantitatively estimated during the early stages of the fire taking into account the anisotropic thermal conductivity of the cells.
