We report direct observation of an unexpected anisotropic swelling of Si nanowires during
lithiation against either a solid electrolyte with a lithium counter-electrode or a liquid …

Rechargeable batteries have a profound impact on our daily life so that it is urgent to capture
the physical and chemical fundamentals affecting the operation and lifetime. The phase-field …

We use a unique transmission electron microscope (TEM) technique to show that Si
nanowires (NWs) with diameters in the range of a few hundred nanometers can be fully …

This paper reports the development of a new stress-dependent chemical potential for solid
state diffusion under multiple driving forces including mechanical stresses. The new stress …

Atomistic simulations of the effects of H on edge dislocation mobility and pile-ups are
performed to investigate possible nanoscale mechanisms for hydrogen-enhanced localized …

In an electrochemical cell, crystalline silicon and lithium react at room temperature, forming
an amorphous phase of lithiated silicon. The reaction front—the phase boundary between …

The embrittlement of metallic systems by hydrogen is a widespread phenomenon but the
precise role of hydrogen in this process is not well understood and predictive mechanisms …
