3-3.5 Li-ion Battery Damage and Fluid Leaks
If
electrolyte solution leakage, or damage such as any problem with the Li-ion battery casing are observed,
first responders should attempt to neutralize the battery by applying a large volume of water to the battery
pack while wearing appropriate PPE. The neutralization process helps stabilize the thermal condition of the
battery pack but does not discharge the battery.
Li-ion Battery Electrolyte Solution Characteristics: • Clear in color
• Sweet odor
• Similar viscosity to water
• Skin irritant
• Eye irritant – If contact with eyes, rinse with plenty of water and see a doctor immediately.
• If electrolyte leak occurs, wear appropriate solvent resistant PPE and use a dry cloth to clean up thespilled electrolyte. Be sure to adequately ventilate the area.
• Highly flammable
• Electrolyte liquid or fumes that have come into contact with water vapors in the air will create an oxidized substance. This substance may irritate skin and eyes. In these cases, rinse with plenty of
water and see a doctor immediately.
• Electrolyte fumes (when inhaled) can cause respiratory irritation and acute intoxication. Move to fresh air and wash mouth with water. See a doctor immediately.
• Since the Li-ion battery is made up of many small sealed battery modules, electrolyte solution leakage should be minimal.
NOTE:
Other fluids in the vehicle (such as engine oil, washer fluid, brake fluid, coolant, etc.) are
the same as those in a conventional vehicle.
