Lithium-ion batteries are becoming more and more predominant
in society. Almost every cell phone, laptop and portable electronic device
today is powered using a lithium-ion battery. Lithium-ion batteries are also
found in power tools, e-bikes, e-scooters, drones, electric vehicles, energy
storage systems, and even spacecraft. If it is rechargeable, the chances are
it’s powered by a lithium-ion battery. The current push towards electrification
will result in an increasing prevalence and reliance on this technology. Most
of the lithium-ion batteries manufactured today are made in China, South Korea,
and other Asian countries. However, there is a significant push to build more
lithium-ion battery manufacturing facilities in North America and Europe. In
fact, at the time of this writing, there are more than 30 ‘giga-factories’
under construction in North America and Europe.
The fire hazards associated with lithium-ion batteries are
well publicized. However, despite a clear recognition of the hazards associated
with them, to date very little sprinklered large scale fire testing has been
conducted to develop appropriate fire protection strategies when present in
significant quantities (e.g., storage, manufacturing, etc.).
This presentation will begin with the
fundamental hazards associated with lithium-ion batteries. It will discuss the
publicly available large-scale fire testing of lithium-ion batteries conducted
to date. It will then describe a recent project wherein a unique fire sprinkler
protection scheme was tested at UL Solutions to assess its ability to mitigate
cell-to-cell thermal runaway propagation in small format lithium-ion batteries
at 100 percent state of charge within a rack-storage configuration. The test
involved approximately 8000 cylindrical cells (18650 form factor) in polypropylene
trays. The array of cells was forced into thermal runaway and the performance
of the sprinkler protection scheme was assessed.
