A. NFPA: Emergency Response to Incident Involving Electric Vehicle Battery Hazards

1. Battery findings: Li-ion has become the dominant rechargeable battery chemistry for consumer electronic devices and is poised to become commonplace for industrial, transportation, and power-storage applications. This chemistry is different from previously popular rechargeable battery chemistries (e.g., nickel metal hydride, nickel cadmium, and lead acid) in a number of ways. From a technological standpoint, because of high energy density, Li-ion technology has enabled the powering of EDVs. From a safety and fire protection standpoint, a high energy density coupled with a flammable organic, rather than aqueous, electrolyte has created a number of new challenges with regard to the design of batteries containing Li-ion cells, and with regard to fire suppression.

2. EDVs are normally silent and also can "hibernate" when the vehicle is stopped. Thus an EDV can be on and ready to propel itself if the accelerator is depressed. Emergency responders can no longer assume that a vehicle is “off” when they cannot hear the engine running.*

3. In the most basic sense, the term Li-ion battery refers to a battery where the negative electrode (anode) and positive electrode (cathode) materials serve as a host for the lithium ion (Li+). Lithium ions move from the anode to the cathode during discharge and are intercalated (inserted into voids) in the crystallographic structure of the cathode. The ions reverse direction during charging, as shown in Figure 1. Since lithium ions are intercalated into host materials during charge or discharge, there is no free lithium metal within a Li-ion cell, thus, if a cell ignites due to external flame impingement or an internal fault, metal fire suppression techniques are not appropriate for controlling the fire.
