In electrochemical energy storage devices, the interface between electrode and electrolyte plays a crucial role. A solid interphase (SEI) is formed on surface due to spontaneous decomposition of electrolyte, which in turn controls dynamics ion migration during charge discharge cycles. However, dynamic nature SEI means that its chemical structure evolves over time as function applied bias; thus, true operando study extremely valuable. X-ray photoelectron spectroscopy (XPS) widely used...
