ABSTRACT:
An electric cell with a lithium/sulphur-dioxide electrolyte complex, corrosive and potentially dangerous, and having automatic protective structural features responsive to excessive internal temperatures or pressures that would be due to internal fault conditions or to external short-circuit conditions, with those protective features serving to selectively vent the cell or to break the internal cell circuit, to prevent explosive rupture of the cell and consequent possible damage to personnel in the adjacent surrounding environment by the corrosive ingredients of the cell.
