Li+ conducting garnet-type oxide sintering triggered by an H+/Li+ ion-exchange reaction
TL;DR: Li et al. as mentioned in this paper proposed a low temperature sintering triggered by an ion exchange reaction (LTI), which promoted element diffusion via limited ion exchange within a range that maintained the crystal structure.

Improved Li6.5La3Zr1.5Nb0.5O12 electrolyte and effects of atmosphere exposure on conductivities
TL;DR: In this paper, a simple modified sol-gel process was used to extract high-quality LLZO ceramics and showed that the ionic conductivity of Li6.5La3Zr1.5Nb0.5O12 gradually decreases to 2.25% after 22 days.

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.
