Investigation of Lithium Sulfur Dioxide (Li/SO2) Battery Safety Hazards -- Chemical Studies.

Abstract

The chemistry associated with the discharge and forced overdischarge of the Li/SO2 cell was investigated in detail. A procedure for the quantitative determination of Li2S2O4 in discharged Li/SO2 cells is described. The amount of Li2S2O4 found in cells discharged to potentials down to zero volt was in very good agreement with the discharge stoichiometry, 2Li + 2SO2 yields Li2S2O4. The Li2S2O4 formed in the carbon cathode was also characterized by infrared, ESCA, and X-ray analyses. A number of organic compounds including CH4 and 3,5-diamino-2,4-hexenenitrile have been identified in forced overdischarged cells. Products identified in cells which vented during forced overdischarge include: CO2, CS2, COS, H2S, CH4, C2H4, C2H2, Li2S, and Li2SO3.
