Sodium/Na β″ Alumina Interface: Effect of Pressure on Voids.
Dominic Spencer Jolly,Ziyang Ning,J. E. Darnbrough,Jitti Kasemchainan,Gareth O. Hartley,Paul Adamson,David E.J. Armstrong,James Marrow,Peter G. Bruce +8 more
TL;DR: 3-electrode studies coupled with tomographic imaging of the Na/Na-β"-alumina interface reveal that voids form in the Na metal at the interface on stripping and they accumulate on cycling, leading to increasing interfacial current density, dendrite formation on plating, short circuit and cell failure.

Correlating the interface resistance and surface adhesion of the Li metal-solid electrolyte interface
Michael Wang,Jeff Sakamoto +1 more
TL;DR: In this paper, the authors combine electrochemical and mechanical characterization to correlate interface kinetics with adhesive strength, and demonstrate that the relationship demonstrated provides a deeper understanding of the mechanical properties of the Li-electrolyte interface, which will play an important role in the design of batteries employing metallic Li anodes.

Electroceramics: Characterization by Impedance Spectroscopy
TL;DR: In this paper, the authors used impedance spectroscopy for unravelling the complexities of such materials, which functions by utilizing the different frequency dependences of the constituent components for their separation, and showed that electrical inhomogeneities in ceramic electrolytes, electrode/electrolyte interfaces, surface layers on glasses, ferroelectricity, positive temperature coefficient of resistance behavior and even ferrimagnetism can all be probed, successfully.

The impact of elastic deformation on deposition kinetics at lithium/polymer interfaces
Charles W. Monroe,John Newman +1 more
TL;DR: In this paper, a Hookeanelastic model is used to compute the additional effect of bulk mechanical forces on electrode stability. But the authors assume that the surface tension resists the amplification of surface roughness at cathodes and show that instability at lithium/liquid interfaces cannot be prevented by surface forces alone.

TL;DR: Synchrotron hard X-ray microtomography experiments on symmetric lithium-polymer-lithium cells cycled at 90 °C show that during the early stage of dendrite development, the bulk of the dendritic structure lies within the electrode, underneath the polymer/electrode interface.
