New energy lithium battery passivation principle diagram

Passivation is a surface protecting reaction which occurs spontaneously in all lithium batteries which are based on a liquid cathode. Passivation prevents the battery from internal short circuit and extends the battery shelf life. The passivation layer increases the internal resistance causing low voltage levels at a load startup quickly

What is lithium passivation?

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.

Why is passivation important in lithium thionyl chloride battery?

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.

Where does passivation occur in a lithium 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?

How does temperature affect the passivation layer of a battery?

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.

Why is the passivation layer important?

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.

Should a battery be de-passivated before use?

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.
