(Note that the anode of a primary lithium battery is lithium and the cathode is graphite, the reverse of Li
Passivation is not recognized as being as aggressive as the chemicals used in pickling. Passivation does not typically go below the surface of the metal and does not change the properties of the metal. The oxide layer left by passivation is only 0.0000001 inches thick, which is very minor. Pickling and Passivation Methods
passivation requirements, with specific emphasis on pressure vessel passivation. We discuss internal failure modes (e.g., battery overcharging, tank over-pressurization) or external causes (e.g., meteoroids and orbital debris, or MOD, impact, solar heating, etc). vehicle does not exceed 0.001 (excluding small particle impacts.).”
Voltage recordings below cut-off would likely trigger a “low battery” warning signal, or worse the current charge could be insufficient to break the passivation layer. This would mean that the cell voltage may never be able to recover to nominal values, which in turn could result in a loss of data to be transmitted or a reset of the device.

What is Passivation of Lithium Battery? Cell passivation is an important characteristic of lithium battery that can be very difficult to understand for many batteries-users. This section discusses this phenomenon, and it gives suggestions on how to counteract the effects of passivation when using lithium batteries. Passivation is a very thin, high resistant, self-assembled layer

Passivation does not remove heavy-scale or oxide layers formed from heat treatment or welding. Pre-cleaning is required for heavily scaled surfaces. Not a Paint Layer: Passivation is not a coating like paint. It forms a thin, invisible oxide layer, but does not add any physical layer to the surface. Does Not Completely Prevent Corrosion:

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?
It is a self-assembled, thin, highly resistant layer of lithium chloride crystals on the surface of the lithium metal. This passivation layer partially blocks the chemical reaction between the solid lithium (anode) and the liquid thionyl chloride (cathode), inhibiting the battery chemical reaction from generating the electrons (electrical current).
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 is a process that “conditions” the battery for proper operation.
This layer is important because it protects the anode from reaction while the cell is dormant – resulting in a long shelf-life. During low rate discharge (5-10 microamps/cm2), the lithium ions that allow the cell to operate can migrate through the passivation layer.
