Current collectors in Li-ion batteries are often considered passive components with minimal influence on performance. However, materials with large expansion during lithiation may influence the current collector. Herein, we demonstrate mechanical deformations of the Cu current collector in Si/graphite electrodes using operando X-ray diffraction.
