The passivation layer on the anode surface is crucial to the electrochemical capacity and lifetime of a lithium-ion battery becauseit is highly stressed with every charging cycle.
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.
Our research indicates that the solid-phase passivation provides a new method to rationally design artificial passivation layers with controlled compositions on lithium metal anodes, which greatly promotes the large-scale production of lithium-metal ASSBs. 4. Experimental 4.1. Preparation of lithium argyrodites
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?
Such phenomena indicate that the passivated lithium has good reversibility and the battery has excellent performance under the condition of high ratio. At the same time, it also shows that the in-situ protective layer formed by SPP inhibits the growth of lithium dendrites, realizing uniform deposition of lithium metal and high current tolerance.
Therefore, solid-phase passivation confers a more stable cycle of lithium anode, which is expected to realize the application of lithium-metal batteries. Fig. 7.

The continuous parasitic reactions (i.e., corrosion) between lithium (Li) and electrolyte gradually exhaust Li supply, leaving batteries of longevity great challenges. Li corrosion relates to Li deposition morphology and characteristics of solid-electrolyte interphase (SEI). Here, we quantitatively detect the Li corrosion, and structural and ...

Passivation. Lithium batteries are affected by a phenomenon known as passivation. Passivation is a film of lithium chloride (LiCl) that forms on the surface of the lithium anode, and it serves to protect the lithium from discharging on its own when the load is removed from the cell. The film of LiCl, which is essentially a high resistance layer between the electrodes, is primarily …
