Investigation of Lithium Sulfur Dioxide (Li/SO2) Battery Safety Hazard
Abstract
The lithium/sulfur dioxide primary electrochemical cell has received considerable attention as a high energy power source in the last decade. However, during the same time a number of safety hazards have been associated with its use. This report is the initial part of a research-oriented investigation intended to identify and document present Li/SO2 safety hazards, then to identify the chemical reactions responsible for these hazards, and finally to investigate methods of controlling them. This report presents the results of a survey of the safety hazards associated with Li/SO2 cells. The report documents specific safety incidents experienced with Li/SO2 cells, presents some of the causes identified or postulated for the incidents, and identifies general aspects of Li/SO2 use presently believed to be potentially hazardous. The survey was carried out by reviewing safety studies and reports of safety incidents appearing in the literature and by gathering unpublished information of the experiences of users of Li/SO2 cells in both government and industry. The results of the report can serve as basis for deciding which aspects of the Li/SO2 safety hazard at present need further investigation.
