Measurement of Volume Changes and Associated Stresses in Ge Electrodes Due to Na/Na Redox Reactions
Subhajit Rakshit, Akshay S. Pakhare, Olivia Ruiz +5
In situ electrochemical cells were assembled with an amorphous germanium (a-Ge) film as working electrode and sodium foil as reference and counter electrode. The stresses generated…
Effect of Decreasing Cobalt Content on the Electrochemical Properties and Structural Stability of Li_(1-x)Ni_(y)Co_(z)Al_(0.05)O_(2) Type Cathode Materials
Kamalika Ghatak, Hemant Kumar, Siva Nadimpalli +1
In Lithium ion batteries (LIBs), proper design of cathode materials influences its intercalation behavior, overall cost, structural stability, and its impact on environment. At pre…
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-…
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…
