Water entry of deformable spheres
Randy C. Hurd, Jesse Belden, Michael A. Jandron +3
When a rigid body collides with a liquid surface with sufficient velocity, it creates a splash curtain above the surface and entrains air behind the sphere, creating a cavity below…
Experimental calibration of a Cahn-Hilliard phase-field model for phase transformations in Li-Sn electrodes
Srivatsan Hulikal, Chun-Hao Chen, Eric Chason +1
Experiments, numerical simulations, and analytical calculations are used to calibrate a diffuse-interface Cahn-Hilliard model of Li-Sn thin film electrodes that experience a transf…
Stress Evolution in Lithium-ion Composite Electrodes during Electrochemical Cycling and Resulting Internal Pressures on the Cell Casing
Siva P. V. Nadimpalli, Vijay A. Sethuraman, Daniel P. Abraham +2
Composite cathode coatings made of a high energy density layered oxide (Li1.2Ni0.15Mn0.55Co0.1O2, theoretical capacity ~377 mAh/g), polyvinylidene fluoride (PVdF) binder, and elect…
Measurement and modeling of the mechanical and electrochemical response of amorphous Si thin film electrodes during cyclic lithiation
Giovanna Bucci, Siva P. V. Nadimpalli, Vijay A. Sethuraman +2
A combination of experimental measurements and numerical simulations are used to characterize the mechanical and electrochemical response of thin film amorphous Si electrodes durin…
On plastic deformation and fracture in Si films during electrochemical lithiation/delithiation cycling
Siva P. V. Nadimpalli, Vijay A. Sethuraman, Giovanna Bucci +3
An in situ study of deformation, fracture, and fatigue behavior of silicon as a lithium-ion battery electrode material is presented. Thin films (100-200 nm) of silicon are cycled i…
Stress Evolution in Composite Silicon Electrodes during Lithiation/Delithiation
Vijay A. Sethuraman, Annam Nguyen, Michael J. Chon +6
We report real-time average stress measurements on composite silicon electrodes made with two different binders [Carboxymethyl cellulose (CMC), and polyvinylidene fluoride (PVDF)]…
Real-Time Stress Measurements in Lithium-ion Battery Negative-electrodes
Vijay A. Sethuraman, Nathan Van Winkle, Daniel P. Abraham +2
Real-time stress evolution in a graphite-based lithium-ion battery negative-electrode during electrolyte wetting and electrochemical cycling is measured through wafer-curvature met…
In Situ Measurements of Stress-Potential Coupling in Lithiated Silicon
Vijay A. Sethuraman, Venkat Srinivasan, Allan F. Bower +1
An analysis of the dependence of electric potential on the state of stress of a lithiated-silicon electrode is presented. Based on the Larché and Cahn chemical potential for a soli…
A Finite Strain Model of Stress, Diffusion, Plastic Flow and Electrochemical Reactions in a Lithium-ion Half-cell
Allan F. Bower, Pradeep R. Guduru, Vijay A. Sethuraman
We formulate the continuum field equations and constitutive equations that govern deformation, stress, and electric current flow in a Li-ion half-cell. The model considers mass tra…
Untwisting of a Strained Cholesteric Elastomer by Disclination Loop Nucleation
A. C. Callan-Jones, Robert A. Pelcovits, Robert B. Meyer +1
The application of a sufficiently strong strain perpendicular to the pitch axis of a monodomain cholesteric elastomer unwinds the cholesteric helix. Previous theoretical analyses o…
