Studies on lithium-sulfur dioxide (Li/SO) battery safety hazards
The chemistry and thermal behavior of Li/SO/sub 2/ cells have been investigated under conditions of discharge, storage and/or overdischarge. In situ spectroelectrochemical studies have been carried out on anode limited cells at room temperature and at -22/sup 0/C. Accelerating Rate Calorimetry has been used to study Li/SO/sub 2/ cells during and following overdischarge. Lithium-limited cells are shown to be intrinsically safe while cells containing excess lithium have been shown to be capable of undergoing thermal runaway. Proposed reactions responsible for thermal runaway are those of lithium with acetonitrile, electrolyte and/or lithium dithionite and the thermal decomposition of lithium dithionite. Li/SO/sub 2/ cells overdischarged at low temperature pose thermally hazardous conditions.
