Lost in Translation: Simulation-Informed Bayesian Inference Improves Understanding of Molecular Motion From Neutron Scattering
Harry Richardson, Kit McColl, Gøran Nilsen +2
Quasi-elastic neutron scattering (QENS) probes atomic and molecular motion on length and time scales central to catalysis, energy materials, and gas adsorption. However, convention…
Learning Optimal Forms of Constitutive Relations Characterizing Ion Intercalation from Data in Mathematical Models of Lithium-ion Batteries
Lindsey Daniels, Smita Sahu, Kevin J. Sanders +3
Most mathematical models of the transport of charged species in battery electrodes require a constitutive relation describing intercalation of Lithium, which is a reversible proces…
Nonlinear electrochemical impedance spectroscopy for lithium-ion battery model parameterization
T. L. Kirk, A. Lewis-Douglas, D. A. Howey +2
In this work we analyse the local nonlinear electrochemical impedance spectroscopy (NLEIS) response of a lithium-ion battery and estimate model parameters from measured NLEIS data.…
A Single Particle Model with Electrolyte and Side Reactions for degradation of lithium-ion batteries
Ferran Brosa Planella, W. Dhammika Widanage
Battery degradation, which is the reduction of performance over time, is one of the main roadblocks to the wide deployment of lithium-ion batteries. Physics-based models, such as t…
Cracking predictions of lithium-ion battery electrodes by X-ray computed tomography and modelling
Adam M. Boyce, Emilio Martínez-Pañeda, Aaron Wade +5
Fracture of lithium-ion battery electrodes is found to contribute to capacity fade and reduce the lifespan of a battery. Traditional fracture models for batteries are restricted to…
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…
