## Title

- title: "<i>Operando</i> Nanomechanical Mapping of Amorphous Silicon Thin Film Electrodes
    in All-Solid-State Lithium-Ion Battery Configuration during Electrochemical Lithiation
    and Delithiation"

## Description

- description: An operando bimodal atomic force microscopy system was constructed
    to perform nanomechanical mapping of an amorphous Si thin film electrode deposited
    on a Li6.6La3Zr1.6Ta0.4O12 solid electrolyte sheet during electrochemical lithiation/delithiation.
    The evolution of Young’s modulus maps of the Si electrode was successfully tracked
    as a function of apparent Li content x in lithium silicide (LixSi) simultaneously
    with real-time surface topography observation. At the initial stage of lithiation,
    the average modulus steeply decreased due to the generation of LixSi from intrinsic
    Si, followed by a moderate modulus reduction until the electrode capacity reached
    3300 mAh g–1 (Li content x = 3.46). In the following delithiation, the gradual
    recovery of the average modulus of LixSi was observed up to 1467 mAh g–1 (Li content
    x = 1.54) at which delithiation stopped due to the significant volume change induced
    by phase transformation of LixSi.
