Lithium-Sulfur Dioxide (Li/SO2) Battery Safety Hazards - Thermal Studies.
Abstract
In this program, the Accelerating Rate Calorimeter (ARC) has been employed to study the thermal and pressure behavior of exothermic reactions occurring in Li/SO2 cells under the conditions of (1) forced overdischarge at ambient temperature, (2) resistive overdischarge at ambient temperature, (3) forced overdischarge at -35 C, and (4) discharge at -35 C. Detected reactions have been characterized in terms of self-heating rate, rate of pressure generation, magnitude of overall heat generation, magnitude of overall pressure rise, and kinetic parameters including activation energy and reaction order. Micro-calorimeter studies determined the heat of reaction for the lithium/acetonitrile reaction to be -54 + or - 1.0 kcal/mole-Li. Lithium/aluminum alloy was found to be unreactive with acetonitrile at ambient temperature. Preliminary investigations were also carried out using FTIR spectroscopy to study the products of electrolyte oxidation on nickel and stainless steel electrodes. (Author)
