Characterization of Reactions and Products of the Discharge and Forced Overdischarge of Li / SO 2 Cells

A procedure for the quantitative determination of in discharged cells is described. The amount of found in cells discharged to potentials down to zero volt was in very good agreement with the discharge stoichiometry, . The has been further characterized by infrared, ESCA, and X‐ray analyses. A number of organic compounds including and 3,5‐diamino‐2,4‐hexenenitrile have been identified in forced overdischarged cells. Products identified in cells that vented during forced overdischarge include: , , , , , , , , and .
