Abstract:
    The invention relates to a method for simulating high-temperature safety property of lithium battery. Wherein, it is characterized in that: (1), first preparing lithium battery pole sample; (2), using one heat measure (as insulated acceleration heat measure) to obtain the temperature increase speed along temperature change of sample; (3) using test to build reaction dynamic model, to build dynamic equation of pole insulated decomposition reaction, using heat measure to test the sample data to obtain the reaction dynamic parameters; (4) using said equation and parameters to calculate out the relation between temperature increase speed and temperature change when discomposing pole material in same electrolyte, any initial temperature and any amount; (5), using Matlab to program and simulate it in computer.
