title = "In-operando X-ray tomography study of lithiation induced delamination of Si based anodes for lithium-ion batteries",
abstract = "Silicon-Lithium based rechargeable batteries offer high gravimetric capacity. However cycle life and electrode microstructure failure mechanisms remain poorly understood. Here we present an X-ray tomography method to investigate in-operando lithiation induced stress cracking leading to the delamination of a composite Si based electrode. Simultaneous voltage measurements show increased cell resistance correlating with severe delamination and microstructural changes. 3D analysis revealed 44.1% loss of the initial electrode-current collector area after 1 hour of operation at 2.4 mA/cm 2 and a 21.2% increase in new anode surface area. The work represents a new basis for future investigation of Si based anodes.",
