Autor: Roby Gauthier, B. Scott, J. Craig Bennett, Mina Salehabadi, Jun Wang, Tariq Sainuddin, M.N. Obrovac
Publikováno v: Heliyon, Vol 10, Iss 15, Pp e34881- (2024)
The transformation of crystalline silicon to amorphous silicon during ball milling was quantitatively measured by x-ray diffraction and electrochemical methods. Amorphous silicon was found to form rapidly from the very initial stages of ball milling.

Autor: Roby Gauthier, Han Ding, Huang Zhenyu, Yue Shen, Yunhui Huang, Michel B. Johnson, J. R. Dahn, J. E. Harlow, Zhe Deng, Aidan Luscombe
Publikováno v: Joule. 4:2017-2029
Summary An ultrasonic imaging technique has been developed to investigate the internal changes of pouch cells nondestructively. The local ultrasonic transmittance of pouch cells has been measured and used for imaging with a new ultrasonic scanning ma

How do Depth of Discharge, C-rate and Calendar Age Affect Capacity Retention, Impedance Growth, the Electrodes, and the Electrolyte in Li-Ion Cells?
Autor: Roby Gauthier, Aidan Luscombe, Toby Bond, Michael Bauer, Michel Johnson, Jessie Harlow, Alex Louli, Jeff R Dahn
Publikováno v: Journal of The Electrochemical Society.
Lithium-ion cells testing under different state of charge ranges, C-rates and cycling temperature have different degrees of lithium inventory loss, impedance growth and active mass loss. Here, a large matrix of polycrystalline NMC622/natural graphite

New Chemical Insights into the Beneficial Role of Al2O3 Cathode Coatings in Lithium-ion Cells
Autor: A. Eldesoky, Vivian S Murray, J. R. Dahn, David S. Hall, Roby Gauthier
Publikováno v: ACS Applied Materials & Interfaces. 11:14095-14100
Inorganic surface coatings such as Al2O3 are commonly applied on positive electrode materials to improve the cycling stability and lifetime of lithium-ion cells. The beneficial effects are typically attributed to the chemical scavenging of corrosive

In-Situ Computed Tomography of Particle Microcracking and Electrode Damage in Cycled NMC622/Graphite Pouch Cell Batteries
Autor: Toby Bond, Roby Gauthier, Sergey Gasilov, J. R. Dahn
Publikováno v: Journal of The Electrochemical Society. 169:080531
Mechanical degradation of electrode materials is an important failure mode in lithium-ion batteries. High-energy-density cathode materials like nickel-rich NMC (LiNixMnyCozO2) undergo significant anisotropic volume expansion during cycling that appli

In Situ Imaging of Electrode Thickness Growth and Electrolyte Depletion in Single-Crystal vs Polycrystalline LiNixMnyCozO2/Graphite Pouch Cells using Multi-Scale Computed Tomography
Autor: Toby Bond, Roby Gauthier, A. Eldesoky, Jessie Harlow, J. R. Dahn
Publikováno v: Journal of The Electrochemical Society. 169:020501
Single-crystal LiNixMnyCozO2 (NMC) materials have recently garnered significant academic and commercial interest as they have been shown to provide exceptional long-term charge-discharge cycling stability in Li-ion cells. Understanding the degradatio
