Saddle-node bifurcation in interfacial morphology selects battery degradation phase
Changdeuck Bae
We propose a minimal nonlinear closure ODE for the dynamic active-area factor of a battery interface and show that it exhibits a saddle-node bifurcation when the smoothing rate sat…

Parabolic-growth universality and its nucleation-driven breakdown across lithium-battery anode chemistries
Changdeuck Bae
Solid-electrolyte interphase (SEI) growth is widely modeled cell-by-cell with chemistry-specific closures, yet its underlying kinetic scaling is rarely tested across chemistries. B…
