Effect of Shrapnel Penetration on Lithium-Carbon Monofluoride and Lithium-Manganese Dioxide Batteries

摘要

National BR2/3A lithium-carbon monofluoride and Duracell DL2/3A lithium-manganesedioxide batteries were subjected to simulated shrapnel penetration using a projectile from an M16 rifle. Trials were conducted on batteries in various states of charge (0, 50, and 100 percent discharged) in both wet and dry environments. Only one fully charged Duracell Battery (under wet conditions) caught fire during the test. The effects of environmental conditions, the chemical reactions involved, and the state of charge of the batteries on the probability of the batteries igniting are discussed.
