Electrodeposition and stripping are fundamental electrochemical processes for metals and have gained importance in rechargeable Li-ion batteries due to lithium metal electrodes. The electrode kinetics associated with lithium metal electrodeposition and stripping is crucial in determining the performance at fast discharge and charge, which is important for electric vertical takeoff and landing (eVTOL) aircraft and electric vehicles (EV). In this work, we show the use of Marcus-Hush-Chidsey (MHC…

Deformed Butler–Volmer Models for Convex Semilogarithmic Current-Overpotential Profiles of Li-ion Batteries
The Butler-Volmer (BV) equation links the current flux crossing an electrochemical interface to the electric potential drop across it with the assumption of Arrhenius kinetics and the Boltzmann
Modeling cyclic voltammetry during solid electrolyte interphase formation: Baseline scenario of a dynamically evolving tunneling barrier resulting from a homogeneous single-phase insulating film.
A baseline quantitative model within Butler-Volmer electrode kinetics is developed, which describes the cyclic voltammetry (CV) of a flat macroelectrode during SEI growth, which forms a homogeneous single-phase electronically insulating thin film due to the corresponding current.
Parameterising continuum level Li-ion battery models&the LiionDB database
The Doyle–Fuller–Newman framework is the most popular physics-based continuum-level description of the chemical and dynamical internal processes within operating lithium-ion-battery cells. With


Charge transfer kinetics at the solid-solid interface in porous electrodes.
A simple method is reported to extract the charge transfer rates in carbon-coated LiFePO4 porous electrodes from chronoamperometry experiments, obtaining curved Tafel plots that contradict the Butler-Volmer equation but fit the Marcus-Hush-Chidsey prediction over a range of temperatures.
Physicochemical Concepts of the Lithium Metal Anode in Solid-State Batteries.
This review assesses the physicochemical concepts that describe the fundamental mechanisms governing lithium metal anode performance in combination with inorganic solid electrolytes and discusses kinetic rate limitations and morphological stability to stimulate further progress in the field of lithiumMetal anodes.
Mesoscale Complexations in Lithium Electrodeposition.
This study deduces that Li deposition morphology evolution is determined by the mesoscale complexations that underlie due to local electrochemical reaction, Li surface self-diffusion, and Li-ion transport in the electrolyte and demonstrates that the substrate surface roughness strongly affects dendritic growth localization over the protrusive surface features.
Distinguishing Li+ Charge Transfer Kinetics at NCA/Electrolyte and Graphite/Electrolyte Interfaces, and NCA/Electrolyte and LFP/Electrolyte Interfaces in Li-Ion Cells
In examining the Li + charge transfer kinetics at the graphite anode and the lithium nickel cobalt aluminum oxide, LiNi0.80Co0.15Al0.05O2 (NCA), cathode in a full cell, we found that the activation
Dendrites and Pits: Untangling the Complex Behavior of Lithium Metal Anodes through Operando Video Microscopy
A comprehensive understanding of the voltage variations observed during Li metal cycling is presented, which is directly correlated to morphology evolution through the use of operando video microscopy, and an improved understanding of changes in cell voltage is presented.
Critical stripping current leads to dendrite formation on plating in lithium anode solid electrolyte cells
The pressure dependence on stripping indicates that creep rather than Li diffusion is the dominant mechanism transporting Li to the interface, which is a major factor limiting the power density of Li anode solid-state cells.
Chemistry, Impedance, and Morphology Evolution in Solid Electrolyte Interphase Films during Formation in Lithium Ion Batteries
The solid electrolyte interphase (SEI) forms during the initial cycles in lithium ion batteries and evolves throughout the battery life. By protecting the electrode and passing lithium ions, the SEI
