Abstract
En 中文
The quality of the solid-electrolyte interphase is crucial for the performance of most battery chemistries, but its formation dynamics during operation are not well understood due to a lack of reliable operando characterization techniques. Herein, we report a dynamic, non-invasive, operando reflection interference microscope to enable the real-time imaging of the solid-electrolyte interphase during its formation and evolution processes with high sensitivity. The stratified structure of the solid-electrolyte interphase formed during four distinct steps includes the emergence of a permanent inner inorganic layer enriched in LiF, a transient assembly of an interfacial electrified double layer and a consequent emergence of a temporary outer organic-rich layer whose presence is reversible with electrochemical cycling. Reflection interference microscope imaging reveals an inverse correlation between the thicknesses of two interphasial subcomponents, implying that the permanent inorganic-rich inner layer dictates the organic-rich outer layer formation and lithium nucleation. The real-time visualization of solid-electrolyte interphase dynamics provides a powerful tool for the rational design of battery interphases. Reflection interference microscopy provides dynamic, non-invasive, operando imaging capabilities that enable the solid-electrolyte interphase formation and evolution of a battery to be mapped in real time with high sensitivity.
