Nucleation of voids at Li-metal–ceramic–electrolyte interfaces

A Correction to this article was published on 21 September 2021

This article has been updated


Electrical currents that are locally concentrated due to spatially variable interface resistance at the lithium-metal–ceramic–electrolyte interface can lead to the nucleation of voids. The Gibbs free energy barrier to nucleation is derived in terms of the electrochemical driving force, which favors, and the interfacial energies, which oppose the development of an embryo, the first step in the formation of a void. Nucleation can be suppressed by low values of the area-specific resistance (ASR) of the cell, and by chemical design of the interface that produces a high value for the contact angle. It is proposed that void nucleation is the precursor to the formation of dendrites.
