Surface Structural Disordering in Graphite upon Lithium Intercalation/Deintercalation
Vijay A. Sethuraman, Laurence J. Hardwick, Venkat Srinivasan +1
We report on the origin of the surface structural disordering in graphite anodes induced by lithium intercalation and deintercalation processes. Average Raman spectra of graphitic…
In Situ Measurements of Stress Evolution in Silicon Thin Films During Electrochemical Lithiation and Delithiation
Vijay A. Sethuraman, Michael J. Chon, Maxwell Shimshak +2
We report in situ measurements of stress evolution in a silicon thin-film electrode during electrochemical lithiation and delithiation by using the Multi-beam Optical Sensor (MOS)…
Analysis of Sulfur Poisoning on a PEM Fuel Cell Electrode
Vijay A. Sethuraman, John W. Weidner
The extent of irreversible deactivation of Pt towards hydrogen oxidation reaction (HOR) due to sulfur adsorption and subsequent electrochemical oxidation is quantified in a functio…
Lithium Diffusion in Graphitic Carbon
Kristin Persson, Vijay A. Sethuraman, Laurence J. Hardwick +6
Graphitic carbon is currently considered the state-of-the-art material for the negative electrode in lithium-ion cells, mainly due to its high reversibility and low operating poten…
In situ Measurement of Biaxial Modulus of Si Anode for Li-ion Batteries
Vijay A. Sethuraman, Michael J. Chon, Maxwell Shimshak +2
We report in situ measurement of biaxial moduli of a Si thin-film electrode as a function of its lithium concentration. During lithiation, biaxial compressive stress is induced in…
In Situ Measurements of Stress-Potential Coupling in Lithiated Silicon
Vijay A. Sethuraman, Venkat Srinivasan, Allan F. Bower +1
An analysis of the dependence of electric potential on the state of stress of a lithiated-silicon electrode is presented. Based on the Larché and Cahn chemical potential for a soli…
