摘要

The limiting oxygen concentration (LOC) method in conjunction with a wick burner, called wick-LOC method, is used to determine the flame stability limits of Li-ion battery electrolyte solvents with organophosphorus compounds (OPCs) addition. Two modes of wick-stabilized flame are found, namely, wake flame and full flame. With the addition of OPC, two distinct extinction behaviors occur according to the different flame modes near extinction. The flame stability limits are measured as a function of OPC addition for both flame modes. The wake flame is shown to be consistently more stable at low levels of OPC addition. However, once the OPC addition exceeds a critical amount, the full flame shows higher stability with a lower LOC than the wake flame. In the most stable flame mode, the regime switches from the wake flame to the full flame with increasing OPC addition, and they are defined correspondingly as 'blow-off regime' and 'quenching regime'.
