Investigation of Initial Lithiation of Silicon (100) Using Solid-State 7Li NMR
Myeonghun Song, Siva P. V. Nadimpalli, Vijay A. Sethuraman +3
Structural changes in amorphous LixSi during the initial lithiation of single crystal Si to amorphous LixSi were investigated as a function of Li flux and total charge using solid-…
On the Role of Elastic Strain on Electrocatalysis of Oxygen Reduction Reaction on Pt
Vijay A. Sethuraman, Deepa Vairavapandian, Manon C. Lafouresse +7
The effect of elastic strain on catalytic activity of platinum (Pt) towards oxygen reduction reaction (ORR) is investigated through de-alloyed Pt-Cu thin films; stress evolution in…
Stress Evolution in Lithium-ion Composite Electrodes during Electrochemical Cycling and Resulting Internal Pressures on the Cell Casing
Siva P. V. Nadimpalli, Vijay A. Sethuraman, Daniel P. Abraham +2
Composite cathode coatings made of a high energy density layered oxide (Li1.2Ni0.15Mn0.55Co0.1O2, theoretical capacity ~377 mAh/g), polyvinylidene fluoride (PVdF) binder, and elect…
Real-time Stress Measurements in Germanium Thin Film Electrodes during Electrochemical Lithiation/delithiation Cycling
Siva P. V. Nadimpalli, Rajasekhar Tripuraneni, Vijay A. Sethuraman
An in situ study of stress evolution and mechanical behavior of germanium as a lithium-ion battery electrode material is presented. Thin films of germanium are cycled in a half-cel…
