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…
Accelerating Cathode Material Discovery through Ab Initio Random Structure Searching
Bonan Zhu, Ziheng Lu, Chris J. Pickard +1
The choice of cathode material in Li-ion batteries (LIBs) underpins their overall performance. Discovering new cathode materials is a slow process, and all major commercial cathode…
Operando monitoring of single-particle kinetic state-of-charge heterogeneities and cracking in high-rate Li-ion anodes
Alice J. Merryweather, Quentin Jacquet, Steffen P. Emge +3
Recent years have seen a rapidly escalating demand for battery technologies capable of storing more energy, charging more quickly and having longer usable lifetimes, driven largely…
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…
