Are lithium-ion batteries flammable?

Fire Hazard of Lithium-ion Battery Energy Storage Systems: 1. Module to Rack-scale Fire Tests Lithium-ion batteries (LIB) are being increasingly deployed in energy storage systems (ESS) due to a high energy density. However, the inherent flammability of current LIBs presents a new challenge to fire protection system design.

Why are lithium-ion batteries used in electrochemical energy storage technology?

It is well known that lithium-ion batteries (LIBs) are widely used in electrochemical energy storage technology due to their excellent electrochemical performance. As the LIBs energy density is become more and more demanding, the potential electrode material failure and external induced risks also increase.

What are the NFPA 855 fire-fighting considerations for lithium-ion batteries?

For example, an extract of Annex C Fire-Fighting Considerations (Operations) in NFPA 855 states the following in C.5.1 Lithium-Ion (Li-ion) Batteries: Water is considered the preferred agent for suppressing lithium-ion battery fires.

Should lithium-ion storage batteries be protected?

Recently issued standards and regulations for lithium-ion storage battery systems now explicitly require protection to prevent and/or control thermal runaways leading to possible deflagrations. Other recently imposed measures are intended to limit electrical fault energies in battery control units.

Are Lib-ESS batteries a fire protection system?

LIB-ESSs contain a large quantity of batteries and have high energy density. Understanding the burning behavior of these systems is critical to proper fire protection system design. To facilitate this effort, a series of small- to large-scale fire tests were conducted using ESS comprised of either LFP or LNO/LMO batteries.

Is lithium-ion battery energy storage safe?

Large-scale, commercial development of lithium-ion battery energy storage still faces the challenge of a major safety accident in which the battery thermal runaway burns or even explodes. The development of advanced and effective safety prevention and control technologies is an important means to ensure their safe operation.
