Which type of battery is primarily associated with the phenomenon of thermal runaway?

• A. Lead-acid battery
• B. Lithium-ion battery
• C. Nickel-cadmium battery
• D. Nickel-metal hydride battery

Answer: (C)

The phenomenon of thermal runaway is primarily associated with lithium-ion batteries. This occurs when a cell in a lithium-ion battery experiences excessive heating, often due to internal shorts or other failure modes, leading to a rapid increase in temperature. This temperature rise can cause further reactions that release more heat, resulting in a potential cascade effect that may lead to venting, smoke, or even fire. Lithium-ion batteries, due to their high energy density and the chemical processes involved, are especially susceptible to this condition. While lead-acid, nickel-cadmium, and nickel-metal hydride batteries can experience overheating and other failure modes, they do not exhibit the same runaway reaction that is characteristic of lithium-ion technology. Therefore, recognizing thermal runaway as a critical risk in lithium-ion batteries is essential for safety and proper management in various applications.
