Transmission line deconvolution separates pore liquid salt diffusion from interfacial kinetics, isolating high-rate transport bottlenecks before thermal runaway.
Eliminating lithium plating in fast-charging silicon anodes requires reducing out-of-plane tortuosity and maintaining stack pressure between 0.3 and 0.8 MPa.
Active anode potential tracking prevents metallic lithium plating, extending cell life and enabling safe 15-minute fast charging in high-power battery packs.
Dynamic anode potential control above 50 mV suppresses crystalline silicide formation, preserving amorphous silicon structure and extending cycle life.
Subzero fast charging induces metallic lithium plating detectable via mid-frequency impedance arc splitting and phase angle drops near zero degrees.
Electro-thermal degradation modeling reveals that internal thermal gradients accelerate localized lithium plating and active inventory loss during fast charging.
Non-linear mechanical stress shifts Butler-Volmer kinetics in high-silicon anodes, lowering nucleation barriers and driving local lithium plating under stack pressure.
Fast-charge thermal gradients and cell swelling drive cyclic shear rupture in cooling plate adhesives, preventable only through compliance-driven joint thickness control.
Dynamic fast-charge swelling pressure in structural cell-to-pack enclosures requires bounded preloads to suppress lithium plating without crushing separators.
Fast charging requires negative electrode potential monitoring above zero volts against lithium reference to prevent cell degradation and thermal risks.
Dynamic intra-cell thermal gradients generate thermoelectric voltage noise that masks lithium plating signals; decoupling algorithms isolate true stripping.
Core-to-surface thermal gradients in prismatic cells drive localized plating and SEI growth, requiring 3D electro-thermal models to prevent early fade.
