A treatment of particle-electrolyte sharp interface fracture in solid-state batteries with multi-field discontinuities
Xiaoxuan Zhang, Tryaksh Gupta, Zhenlin Wang +3
In this work, we present a computational framework for coupled electro-chemo-(nonlinear) mechanics at the particle scale for solid-state batteries. The framework accounts for inter…
Ferroelastic toughening: can it solve the mechanics challenges of solid electrolytes?
Anton Van der Ven, Robert M. McMeeking, Raphaële J. Clément +1
The most promising solid electrolytes for all-solid-state Li batteries are oxide and sulfide ceramics. Current ceramic solid electrolytes are brittle and lack the toughness to with…
LiCoO phase stability studied by machine learning-enabled scale bridging between electronic structure, statistical mechanics and phase field theories
Gregory H. Teichert, Sambit Das, Muratahan Aykol +3
LiO (TM={Ni, Co, Mn}) are promising cathodes for Li-ion batteries, whose electrochemical cycling performance is strongly governed by crystal structure and phase stability…
Modeling strength and failure variability due to porosity in additively manufactured metals
M. Khalil, G. H. Teichert, C. Alleman +4
To model and quantify the variability in plasticity and failure of additively manufactured metals due to imperfections in their microstructure, we have developed uncertainty quanti…
Machine learning materials physics: Integrable deep neural networks enable scale bridging by learning free energy functions
G. H. Teichert, A. R. Natarajan, A. Van der Ven +1
The free energy of a system is central to many material models. Although free energy data is not generally found directly, its derivatives can be observed or calculated. In this wo…
Multi-physics simulations of lithiation-induced stress in LiTiO electrode particles
Tonghu Jiang, Shiva Rudraraju, Anindya Roy +3
Cubic spinel LiTiO is a promising electrode material as it exhibits a high lithium diffusivity and undergoes minimal changes in lattice parameters during lithia…
