Real-time stress measurements in lithium-ion battery negative-electrodes

Highlights Real-time stress evolution in a practical lithium-ion electrode is reported for the first time. Upon electrolyte addition, the electrode rapidly develops compressive stress (ca. 1–2 MPa). During intercalation at a slow rate, compressive stress increases with SOC up to 10–12 MPa. De-intercalation at a slow rate results in a similar …
