Which statement accurately describes hazards of lithium-based batteries?

• A. They are safe
• B. They cannot react with water
• C. They never experience thermal runaway
• D. They are hazardous material and a fire hazard

Answer: (C)

Lithium-based batteries carry significant safety risks because they can experience thermal runaway, a chain reaction where overheating within a cell causes it to generate more heat, potentially leading to venting, fire, and even explosion. This can happen if the cell is damaged, shorted, overcharged, or exposed to high temperatures. The electrolyte is flammable, and gases released during venting can ignite, turning a small fault into a major fire hazard. Because of these dangers, lithium batteries are treated as hazardous material and require careful handling, storage away from heat and conductive exposures, and proper fire suppression measures. Statements that claim they are safe or that they cannot react with water are incorrect, and the risk of thermal runaway means they can indeed pose serious fire hazards under certain conditions.
