Passivation is a phenomenon of all lithium primary cells related to the interaction of the metallic lithium anode and the electrolyte. A thin passivation layer forms on the surface of the anode at the instant the electrolyte is introduced into the cell.
Passivation is a necessary intermediary layer that it inhibits the immediate reaction of the solid lithium anode with the liquid thionyl chloride cathode, thus providing for the stability and very low self-discharge (<3% typical) of the lithium thionyl chloride battery.
Since passivation begins to occur as soon as the lithium metal battery cell is manufactured, it occurs anywhere the cell or battery pack using the cell is located. Thus passivation is occurring naturally in the battery while in transit, in storage, at the shop, at the rig, or downhole even while operating, if current loads are very low. Why?
Higher temperature causes a thicker passivation layer, thus storing at cooler (room) temperature helps mitigate passivation layer growth. Consequently, using fresher batteries helps assure a less resistive passivation layer has formed in the battery. The passivation layer is diminished by appropriate electrical current flow through the cell.
Battery de-passivation should be conducted prior to use of the battery. As mentioned, the passivation layer will always be attempting to grow. So de-passivating the battery a relatively short time (hours to days) before the battery is used will help avail proper lithium surface area to generate the required current for the tool electrical load.
Battery de-passivation is a process that “conditions” the battery for proper operation.
