Opportunities for Rechargeable Solid-State Batteries Based on Li-Intercalation Cathodes
Xabier Judez,Gebrekidan Gebresilassie Eshetu,Chunmei Li,Lide M. Rodriguez-Martinez,Heng Zhang,Michel Armand +5 more
TL;DR: In this article, the attainable energy density, overall safety, and cost for solid-state Li metal-intercalation cathode batteries (ASSLICBs) are presented. And the existing approaches from literature toward the claimed energy density and safety are intensively discussed.

Computational study of lithium nucleation tendency in Li7La3Zr2O12 (LLZO) and rational design of interlayer materials to prevent lithium dendrites
TL;DR: In this paper, density functional theory (DFT) calculations were performed to investigate the ability of the pore surfaces to trap excess electrons, which is essential to Li nucleation tendency, and two interlayer materials were also studied, tetragonal LLZO (t-LLZO) and Li2PO2N (atomic layer deposited LiPON).

Grain Boundary Softening: A Potential Mechanism for Lithium Metal Penetration through Stiff Solid Electrolytes.
Seung Ho Yu,Donald J. Siegel +1 more
TL;DR: It is proposed that inhomogeneities in elastic properties arising from microstructural features provide a mechanism by which soft lithium can penetrate ostensibly stiff solid electrolytes.

Mechanical behavior of Li-ion-conducting crystalline oxide-based solid electrolytes: a brief review
TL;DR: In this paper, the elastic, plastic, and fracture properties of crystalline oxide-based Li-ion solid electrolytes for three different crystal structures: Li6.19Al0.27La3Zr2O12 (garnet) [LLZO], Li0.33La0.57TiO3 (perovskite), and Li1.3Al 0.3Ti1.7(PO4)3 (NaSICON) [LATP].

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.

Detection of subsurface structures underneath dendrites formed on cycled lithium metal electrodes.

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.
