Introduction
Lithium-ion battery technologies are increasingly used in electric vehicles as well for
electrical energy storage at residences, businesses and utilities. In a failure event,
these cells may produce large quantities of gas that pose fire, explosion and toxicity hazards to building occupants and firefighters. To understand the hazard, it
is important to understand how single cells fail and how that failure propagates to
other cells. Once the quantity and composition of the gas released by a single cell is
understood and the failure process to surrounding cells is understood then models
can be applied to quantify the explosion or fire hazard of the system.
Key notes
- Summary of lithium-ion battery gas compositions and flammability properties (see Figure 5.5, Section 5.4 and Table 5.4 ).
- Models for fire and explosion hazard analysis.
