TUT2: Managing and Understanding the Risks of Li-Ion Battery Safety

MONDAY, OCTOBER 28: 10:30 - 12:30

A wide variety of stresses and abuses of Li-ion cells can result in safety events involving significant, and sometimes even violent, energy release and thermal runaway. This tutorial provides a framework for a better understanding of how these safety events occur, how lithium-ion batteries respond to various stresses/abuses, how various stresses can lead to thermal runaway, and why differing stresses produce challenges to assessment of safety characteristics of Li-ion cells. For major types of stress/abuse, a flow chart identifying key process steps and characteristics of cell response helps provide important insights regarding similarities and important differences of various types of safety-related failures. A systematic understanding of similarities and differences of most types of stresses helps provide important perspective regarding management of Li-ion battery safety as well as appropriate safety testing.
