Nanomechanical measurements shed light on solid-state battery degradation
TL;DR: The use of a pure lithium metal anode within solid-state batteries is key for higher energy density, and it is thought that using solidstate electrolytes instead of conventional liquids could increase the chemical and structural stability of lithium metal.

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.
