Insight into the formation and stability of solid electrolyte interphase (SEI) for nanostructured silicon-based anode electrodes used in Li-ion batteries

Silicon-based anode fabrication with nano-scale structuration improves the energy density and life cycle of Li-ion batteries. As-synthesized silicon (Si) nanowires (NWs) or nanoparticles (NPs) directly on the current collector represent a credible alternative to conventional graphite anode. However, the operating potentials of these electrodes are below the electrochemical stability window of all electrolytes used in […]
