  1. LiMnO2 .48Wh LiFeSO2 1.65Wh LiMnO2 1.86Wh LiMnO2 2.25Wh LiFeSO2 4.35Wh LiMnO2 4.65Wh LiSOCl2 8.82Wh LiMnO2 9Wh LiSOCl2 10.8Wh LiSOCl2 30.6Wh LiMnO2 33.3Wh LiSOCl2 68.4Wh Lithium Metal Battery Cells – Risks and Hazards ICAO FAA Fire Safety 09-11-2014

  2. Lithium-Metal: Importance of Vent Thionyl Chloride (Without Vent) Thionyl Chloride (With Vent)

  3. Hazard of Thionyl Chloride (w/o vent) in LD3

  4. Lithium-Metal: Chemistry Variation Thionyl Chloride (With Vent) Sulfur Dioxide (With Vent) Manganese Dioxide (With Vent)

  5. Battery Fires in Reduced O2 Environment • 200 CR123A Manganese Dioxide cells in chamber Air Argon Nitrogen Initial O2: 9% Initial O2: 21% Initial O2: 9% Propagation Time: 187 sec O2 Depletion: 7.25% Max THC: .2237% Max Ave. Chamber Temp. 118.1C Propagation Time: 339 sec O2 Depletion: 3.67% Max THC: .7394% Max Ave. Chamber Temp. 165.5C Propagation Time: 337 sec O2 Depletion: .633% Max THC: .8746% Max Ave. Tree Temp. 37.63C

  6. Summary • Cells without adequate vents can explode. • Heat release, propagation and flammability vary among different chemistries of Lithium-Metal cells. • Propagation of cells is slowed by oxygen depletion with either Argon or Nitrogen • Argon was insufficient to fully prevent the battery fire however.
