Abstract
Disclosed are oxidizer-treated lithium electrodes, battery cells containing such oxidizer-treated lithium electrodes, battery cell electrolytes containing oxidizing additives, and methods of treating lithium electrodes with oxidizing agents and battery cells containing such oxidizer-treated lithium electrodes. Battery cells containing SO as an electrolyte additive in accordance with the present invention exhibit higher discharge capacities after cell storage over cells not containing SO . Pre-treating the lithium electrode with SO gas prior to battery assembly prevented cell polarization. Moreover, the SO treatment does not negatively impact sulfur utilization and improves the lithium's electrochemical function as the negative electrode in the battery cell.
