Абстракт

Disclosed are dioxolane-treated lithium electrodes, battery cells containing such dioxolane-treated lithium electrodes, battery cell electrolytes containing dioxolane, and methods of treating lithium electrodes with dioxolane and battery cells containing such dioxolane-treated lithium electrodes. Treating lithium with dioxolane prevents the lithium from reacting with a wide range of substances which can contaminate battery cells, particularly moisture and other protic impurities, that might otherwise react with the lithium to the detriment of its function as a negative electrode in a battery cell. Battery cells containing dioxolane as an electrolyte co-solvent in accordance with the present invention exhibit improved cycling performance over cells not containing dioxolane. Moreover, the dioxolane treatment does not negatively impact sulfur utilization and improves the lithium's electrochemical function as the negative electrode in the battery cell.
