A Suite of Reduced-Order Models of a Single-Layer Lithium-ion Pouch Cell
Scott G. Marquis, Robert Timms, Valentin Sulzer +2
For many practical applications, fully coupled three-dimensional models describing the behaviour of lithium-ion pouch cells are too computationally expensive. However, owing to the…
The effect of mechanical stress on lithium distribution and geometry optimisation for multi-material lithium-ion anodes
Ian P. E. Roper, S. Jon Chapman, Colin P. Please
A model is presented for predicting the open-circuit voltage (OCV) and lithium distribution within lithium-ion anodes containing multiple materials, coupling linear elasticity with…
An asymptotic derivation of a single particle model with electrolyte
Scott G. Marquis, Valentin Sulzer, Robert Timms +2
The standard continuum model of a lithium-ion battery, the Doyle-Fuller-Newman (DFN) model, is computationally expensive to solve. Typically simpler models, such as the single part…
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…
