摘要

光纤布拉格光栅被用作两种具有代表性的固态电极的原位应力传感器。在纯活性材料微米Si电极中，由于Si的体积变化较大，检测到63.9 MPa的大应力变化。此外，在S复合固态电极中，FBG记录了阶段性的应力变化，这是称重传感器无法检测到的，表明了嵌入式应力传感器的必要性。

Monitoring internal stress variation of solid-state batteries by fiber Bragg grating†

Fiber Bragg grating is utilized as an in situ stress sensor for two representative categories of solid-state electrodes. In the active material-only micron-Si electrode, a large stress variation of 63.9 MPa was detected due to the substantial volume change of Si. In addition, a staged stress change was recorded by FBG in the S composite solid-state electrode, which was undetectable by the load cell, indicating the necessity of the embedded stress sensor.
