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…
Lithium-ion battery degradation: how to model it
Simon E. J. O'Kane, Weilong Ai, Ganesh Madabattula +7
Predicting lithium-ion battery degradation is worth billions to the global automotive, aviation and energy storage industries, to improve performance and safety and reduce warranty…
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…
Degradation of Layered Oxide Cathode in a Sodium Battery: A Detailed Investigation by X-Ray Tomography at the Nanoscale
Daniele Di Lecce, Vittorio Marangon, Mark Isaacs +3
The degradation mechanism in a sodium cell of a layered Na0.48Al0.03Co0.18Ni0.18Mn0.47O2 (NCAM) cathode with P3/P2 structure is investigated by revealing the changes in microstruct…
Reduced variance analysis of molecular dynamics simulations by linear combination of estimators
Samuel W. Coles, Etienne Mangaud, Daan Frenkel +1
Building upon recent developments of force-based estimators with a reduced variance for the computation of densities, radial distribution functions or local transport properties fr…
Physical modelling of the slow voltage relaxation phenomenon in lithium-ion batteries
Toby Kirk, Colin P. Please, S. Jon Chapman
In the lithium-ion battery literature, discharges followed by a relaxation to equilibrium are frequently used to validate models and their parametrizations. Good agreement with exp…
