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 Composite Silicon Electrodes during Lithiation/Delithiation
Vijay A. Sethuraman, Annam Nguyen, Michael J. Chon +6
We report real-time average stress measurements on composite silicon electrodes made with two different binders [Carboxymethyl cellulose (CMC), and polyvinylidene fluoride (PVDF)]…
Quantifying Capacity Loss due to Solid-Electrolyte-Interphase Layer Formation on Silicon Negative Electrodes in Lithium-ion Batteries
Siva P. V. Nadimpalli, Vijay A. Sethuraman, Swapnil Dalavi +4
Charge lost per unit surface area of a silicon electrode due to the formation of solid-electrolyte-interphase (SEI) layer during initial lithiation was quantified, and the species…
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)…
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…
Real-time Measurement of Stress and Damage Evolution During Initial Lithiation of Crystalline Silicon
Michael J. Chon, Vijay A. Sethuraman, Anthony McCormick +2
Crystalline to amorphous phase transformation during initial lithiation in (100) silicon-wafers is studied in an electrochemical cell with lithium metal as the counter and referenc…
