This paper describes the results from simulations of laminar burning velocities in the premixed air and flammable gases vented from abused Li-ion batteries. The released mixture from such batteries contain mixtures of hydrogen, methane, ethylene, carbon monoxide and carbon dioxide. The study also includes the combustion properties of an electrolyte, dimethyl carbonate. The simulation results show the laminar burning velocities as a function of concentration, pressure and temperature for the gas mixtures and electrolyte. The goal of the present project is to use the simulated burning velocities in curve fitted functions for use in computational fluid dynamics (CFD) codes.

Keywords: Li-ion battery, Safety, Laminar burning velocity
