Structural electroneutrality in Onsager-Stefan-Maxwell transport with charged species
Alexander Van-Brunt, Patrick E. Farrell, Charles W. Monroe
We present a method to embed local electroneutrality within Onsager-Stefan-Maxwell electrolytic-transport models, circumventing their formulation as differential systems with an al…
Finite element methods for multicomponent convection-diffusion
Francis R. A. Aznaran, Patrick E. Farrell, Charles W. Monroe +1
We develop finite element methods for coupling the steady-state Onsager--Stefan--Maxwell equations to compressible Stokes flow. These equations describe multicomponent flow at low…
Anisotropic thermal characterisation of large-format lithium-ion pouch cells
Jie Lin, Howie N. Chu, Charles W. Monroe +1
Temperature strongly impacts battery performance, safety and durability, but modelling heat transfer requires accurately measured thermal properties. Herein we propose new approach…
Parameterising continuum level Li-ion battery models & the LiionDB database
A. A. Wang, S. E. J. O'Kane, F. Brosa Planella +9
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-batter…
Multiscale coupling of surface temperature with solid diffusion in large lithium-ion pouch cells
Jie Lin, Howie N. Chu, David A. Howey +1
Untangling the relationship between reactions, mass transfer, and temperature within lithium-ion batteries enables control approaches that mitigate thermal hot spots and slow degra…
Consolidated theory of fluid thermodiffusion
Alexander Van-Brunt, Patrick E. Farrell, Charles W. Monroe
We present the Onsager--Stefan--Maxwell thermodiffusion equations, which account for the Soret and Dufour effects in multicomponent fluids. Unlike transport laws derived from kinet…
Augmented saddle point formulation of the steady-state Stefan--Maxwell diffusion problem
Alexander Van-Brunt, Patrick E. Farrell, Charles W. Monroe
We investigate structure-preserving finite element discretizations of the steady-state Stefan--Maxwell diffusion problem which governs diffusion within a phase consisting of multip…
A State Observer Design for Simultaneous Estimation of Charge State and Crossover in Self-Discharging Disproportionation Redox Flow Batteries
Pedro Ascencio, Kirk Smith, David Howey +1
This paper presents an augmented state observer design for the simultaneous estimation of charge state and crossover flux in disproportionation redox flow batteries, which exhibits…
An Adaptive Observer Design for Charge-State and Crossover Estimation in Disproportionation Redox Flow Batteries undergoing Self-Discharge
Pedro Ascencio, Kirk Smith, Charles W. Monroe +1
This article considers a model formulation and an adaptive observer design for the simultaneous estimation of the state of charge and crossover flux in disproportionation redox flo…
Faster Lead-Acid Battery Simulations from Porous-Electrode Theory: II. Asymptotic Analysis
Valentin Sulzer, S. Jon Chapman, Colin P. Please +2
Electrochemical and equivalent-circuit modelling are the two most popular approaches to battery simulation, but the former is computationally expensive and the latter provides limi…
Faster Lead-Acid Battery Simulations from Porous-Electrode Theory: I. Physical Model
Valentin Sulzer, S. Jon Chapman, Colin P. Please +2
An isothermal porous-electrode model of a discharging lead-acid battery is presented, which includes an extension of concentrated-solution theory that accounts for excluded-volume…
