Electrochemical Ion Insertion: From Atoms to Devices
Aditya Sood, Andrey D. Poletayev, Daniel A. Cogswell +7
Electrochemical ion insertion involves coupled ion-electron transfer reactions, transport of guest species, and redox of the host. The hosts are typically anisotropic solids with t…
Size-dependent phase morphologies in LiFePO4 battery particles
Daniel A. Cogswell, Martin Z. Bazant
Lithium iron phosphate (LiFePO) is the prototypical two-phase battery material, whose complex patterns of lithium ion intercalation provide a testing ground for theories of ele…
Simulation of incompressible two-phase flow in porous media with large timesteps
Daniel A. Cogswell, Michael L. Szulczewski
Multiphase flow in porous media occurs in several disciplines including petroleum reservoir engineering, petroleum systems' analysis, and CO sequestration. While simulations of…
Toward Quantitative Phase-field Modeling of Dendritic Electrodeposition
Daniel A. Cogswell
A thin-interface phase-field model of electrochemical interfaces is developed based on Marcus kinetics for concentrated solutions, and used to simulate dendrite growth during elect…
Theory of Nucleation in Phase-separating Nanoparticles
Daniel A. Cogswell, Martin Z. Bazant
The basic physics of nucleation in solid \hl{single-crystal} nanoparticles is revealed by a phase-field theory that includes surface energy, chemical reactions and coherency strain…
Coherency strain and the kinetics of phase separation in LiFePO4
Daniel A. Cogswell, Martin Z. Bazant
A theoretical investigation of the effects of elastic coherency on the thermodynamics, kinetics, and morphology of intercalation in single LiFePO4 nanoparticles yields new insights…
Suppression of Phase Separation in LiFePO4 Nanoparticles During Battery Discharge
Peng Bai, Daniel A. Cogswell, Martin Z. Bazant
Using a novel electrochemical phase-field model, we question the common belief that LixFePO4 nanoparticles separate into Li-rich and Li-poor phases during battery discharge. For sm…
Thermodynamic phase-field model for microstructure with multiple components and phases: the possibility of metastable phases
Daniel A. Cogswell, W. Craig Carter
A diffuse-interface model for microstructure with an arbitrary number of components and phases was developed from basic thermodynamic and kinetic principles and formalized within a…
