Mapping internal temperatures during high-rate battery applications
Thomas M. M. Heenan,Isabella Mombrini,Alice V. Llewellyn,Stefano Checchia,Chun Tan,Anmol Jnawali,Gaston Garbarino,Rhodri Jervis,Dan J. L. Brett,Marco Di Michiel,Paul R. Shearing +10 more
TL;DR: In this article , the state of charge, mechanical strain and temperature within lithium-ion 18650 cells operated at high rates (above 3C) were characterized by means of two advanced synchrotron XRD methods: first, as entire cross-sectional temperature maps during open-circuit cooling and second, single point temperatures during charge-discharge cycling.

In-situ X-ray tomographic imaging study of gas and structural evolution in a commercial Li-ion pouch cell
W. Du,Rhodri E. Owen,Anmol Jnawali,Tobias P. Neville,Francesco Iacoviello,Zhenyu Zhang,Sébastien Liatard,Dan J. L. Brett,Paul R. Shearing +8 more
TL;DR: In this article , the structural evolution of a 400 mAh commercial Li-ion pouch cell was observed in 4D (3D + time), and subsequent quantification including volume fraction, surface area and thickness showed a heterogeneous gas distribution, revealing the degradation mechanism involving the coalescence of gas.
Tracking the Lifecycle of a 21700 Cell: A 4D Tomography and Digital Disassembly Study
Anmol Jnawali,James B. Robinson,Matt D. R. Kok,Dan J. L. Brett,Paul R. Shearing,Thomas G. Tranter,Thomas M. M. Heenan +6 more
TL;DR: A 4D tomography study tracks the lifecycle of a 21700 Li-ion cell, revealing a causal relationship between electrode structure changes and capacity fade, highlighting the importance of consistent manufacturing processes and identifying small defects as nucleation sites for degradation.
