摘要

Thermal runaway in lithium-ion battery is a complex and somewhat unpredictable process.With increasing temperature due to abuse,electrode breaks down then oxygen is released which may facilitate the burning of the electrolyte inside the cell,resulting in fire or even explosion.In this paper,an attempt to define a thermochemical abuse model of an 18650 lithium-ion battery cell has been made by using the reactor-network function of ANSYS CHEMKIN.Heat balance in the cell is used to calculate the temperature,pressure and amount of oxygen generated in the cell with time.The onset of self-ignition marks the thermal runaway in the battery.The Chemical kinetic mechanism and thermo-physical properties of a cell have been obtained from the previous work in the laboratory and literature.Two different variants of Organophosphorus compound(OPC)fire retardants were added separately to the electrolyte solvent in increasing concentration.Their resulting effect on fire parameters has been revealed.
