Electro-chemo-mechanics of solids: application to all-solid-state batteries, polyelectrolyte gels, and actuators.
In several solid systems, including batteries and various electrochemically-based actuators, charged ions are transported across a solid host material under the influence of electric fields and concentration gradients, which can cause local volumetric expansion and contraction. Since stresses and …

Ab-initio simulation of novel solid electrolytes
All solid-state batteries may be a solution to some of the problems facing conventional organic electrolytes in Li and Na-ion batteries, but typically conductivities are very low. Reports of fast lithium conduction in Li 0GeP 2S1 2 (LGPS), with conductivity of 12 mS/cm at room temperature, have …

Ionic conductivity transitions in antiperovskite ionic conductors
High-performance solid electrolytes are critical for realizing all-solid-state batteries with enhanced safety and cycling efficiency. However, the relatively low ionic conductivity of most solid state electrolytes has been considered as the major challenge. Antiperovskite(AP) electrolytes are …

Electrochemomechanical fatigue and fracture in electrode and electrolyte materials for Li-Ion batteries
In Li-ion batteries (LIBs), electrochemically driven dimensional changes in the electrodes lead to mechanical stress buildup during operation. Electrochemomechanical fatigue refers to both mechanical degradation (fracture) and the associated chemical degradation that is exacerbated by fracture as a …

A study of the synthesis, structure, and ionic conductivity of sodium and lithium lanthanide pyrosilicates, A3LnSi2O7
… alkali ions. The Na-compounds exhibit four crystallographically distinct alkali-sites whereas the Li-compounds exhibit two such sites, only one of which is equivalent to that in the Na-structure. The new lithium site inhabits an atypical square planar environment. These structural models were …

Tailoring the electrochemical properties of catholytes for solid-state sodium batteries
Sodium-based all-solid-state batteries (ASSBs) represent a promising alternative to lithium-based systems due to their inherent safety and the abundance and low cost of sodium resources. However, their large-scale adoption is hindered by limited solid electrolyte ionic conductivity, poor …

Scalable Processing Routes for Solid-State Energy Conversion and Storage Devices
Solid-state electrochemical devices all have at least one central component in common, an ion-conductive solid electrolyte (SE). The SE is the basis of the design of both all-solid-state batteries (ASSBs) and solid oxide fuel cells (SOFCs) and is a major determinate for their performance and the …
