This process is known as passivation in lithium batteries. Why is passivation important? As a result of the highly resistant film of lithium chloride that forms, the self-discharge rate of lithium cells is low.

Abstract. While lithium–oxygen batteries have a high theoretical specific energy, the practical discharge capacity is much lower due to the passivation of the solid discharge product, Li 2 O 2, on the electrode surface.Herein, we studied and quantified the deposition and dissolution kinetics of Li 2 O 2 using an electrochemical quartz crystal microbalance (EQCM).
During low rate discharge (5-10 microamps/cm2), the lithium ions that allow the cell to operate can migrate through the passivation layer. As the rate of discharge increases (0.1-1.0 milli
Lithium–sulfur batteries (LSBs) have received great attention as promising candidates for next-generation energy-storage systems due to their high theoretical energy density. However, their practical energy density is limited by a large electrolyte-to-sulfur (E/S) ratio (>10 µL electrolyte/mg s), and their cycle performance encounters challenges from electrode
Passivation is the formation of a thin resistive layer on the lithium anode as a result of the chemical reaction between the anode and the electrolyte. This layer reduces the rate of self-discharge of the battery by slowing the reaction between the lithium metal and the electrolyte. The passivation layer due to long term storage can contribute
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 in a lithium thionyl chloride battery cell is a chemical reaction between the solid metallic lithium metal and the liquid catholyte (cathode and electrolyte) in the cell. It is a self-assembled, thin, highly resistant layer of lithium chloride crystals on the surface of the lithium metal.
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.
During low rate discharge (5-10 microamps/cm2), the lithium ions that allow the cell to operate can migrate through the passivation layer. As the rate of discharge increases (0.1-1.0 milli-amp/cm2), so does the porosity of the passivation layer, allowing greater ion flow and higher power output.
Passivation may cause voltage delay after a load is placed on the cell as illustrated in the following drawing: After a load is placed on a cell, the high resistance of the passivation layer causes the cell's voltage to dip. The discharge reaction slowly removes the passivation layer thereby lowering the internal resistance of the cell.
