In situ Measurement of Biaxial Modulus of Si Anode for Li-ion Batteries

open access: yes, 2010
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 the Si film and it undergoes plastic flow. At any state-of-charge (SOC), a
