Abstract
A method for making a primary cell comprising a lithium anode and an iodine containing cathode. The cell is first subjected to a preliminary conditioning at a predetermined time/temperature to effect a reduction in the impedance of the cell followed by cell discharge of at least 2 mAh per cm.sup.2 of the lithium anode surface prior to use or extended storage of the cell. The resulting primary cell has reduced variation in cell voltage and resistance and slower and more consistent self-discharge characteristics.
