Summary

This lecture, part of the Princeton-CEFRC Combustion Summer School, focuses on lithium-ion battery fires. Peter Sunderland begins by highlighting the increasing sales of electric vehicles and the corresponding rise in battery fires, emphasizing the importance of understanding fire safety. He explains the basic anatomy of a lithium-ion battery, detailing the four main components: cathode, anode, separator, and electrolyte. He emphasizes that cathodes contain oxygen, which can be released at high temperatures and react with the flammable electrolyte, leading to thermal runaway. The lecture covers different cathode chemistries (LCO, LFP, NMC, NCA) and their trade-offs in energy density and fire safety. Sunderland discusses safety features such as safety vents, current interrupt devices, and shutdown separators, explaining how they work to prevent catastrophic failure. He also describes the three main triggers for battery fires: thermal, electrical, and mechanical abuse. The lecture concludes with a discussion of thermal runaway using a Semenov plot, illustrating the balance between heat generation and heat loss. Throughout, Sunderland emphasizes the need for continued research and improved safety measures in battery design.
