Effect of Stress State on Phase Stability and Ionic Transport in the Solid Electrolyte Li7La3Zr2O12

Scott Monismith et al.

Summary: This study uses classical molecular dynamics simulations to investigate the relationship between stress state and lithium ion dynamics in LLZO. The results show that the activation energy decreases under hydrostatic tension and increases under hydrostatic compression, with a cubic-to-tetragonal phase change occurring under uniaxial load in the x-direction.

Dislocations in ceramic electrolytes for solid-state Li batteries

L. Porz et al.

Summary: High power solid-state Li batteries face challenges due to dendrite-like structures caused by dislocations. Introducing dislocations to tailor mechanical properties and withstand mechanical stress is a key step. Understanding the mechanics of dislocations in ceramic electrolytes and methods like uniaxial deformation are crucial for this process.

Temperature and radiation effects on brittle versus ductile fracture behavior in miscible phase boundaries: insight from atomistic simulations

Remi Dingreville et al.

Summary: Temperature and irradiation have significant effects on the failure mechanisms in miscible phase boundaries, leading to changes in brittleness and ductility properties. The accumulation of radiation-induced defects plays a key role in the transition between brittle and ductile interfacial fracture mechanisms.
