Ultra-long-life batteries harness the passivation effect

Passivation occurs when a thin film of lithium chloride (LiCl) forms on the surface of the lithium anode to limit chemical reaction. Whenever a load is placed on the cell, the passivation layer also creates an initial high resistance, causing voltage to dip temporarily until the discharge reaction removes the passivation layer.

6 FAQs about [Lithium manganese battery passivation]

What is lithium passivation?

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?

Does a surface passivation layer of Li metal eliminate the side reaction?

As the surface passivation layer of Li metal, SEI can hardly eliminate the side reaction between Li metal and electrolyte interface due to its functional failure , . To simulate the evolution of SEI, the morphologies of SEI before and after soaking for 2 h in the electrolyte have been observed.

Can a lithium thionyl chloride battery de-Pass?

To deal with the natural occurrence of passivation, and also account for the need of tool dynamic current-pulse load performance, one needs to mitigate the effects of passivation by properly de-passivating a lithium thionyl chloride battery, or “de-pass”ing as it called in the drilling industry, before and possibly during use.

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.
