Simple scalable processing method for a polymer/inorganic hybridized electrolyte
TL;DR: In this article, the authors evaluated three different simple processes that may be used to produce composite membranes by examining scanning electron microscope images and measuring conductivity, and the optimal method was 0.49mS/cm at 20°C, which is approximately 5.5 times higher than that of a commercially produced LATP-sintered disk.

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.
