    <jats:title>Abstract</jats:title><jats:p>Changes in the interfacial structures of the amorphous silicon (a-Si) anode/organic electrolyte interfaces in lithium-ion batteries were investigated using highly dense a-Si films fabricated by cathodic arc plasma deposition as a model electrode. Raman spectroscopy, transmission electron microscopy (TEM), and X-ray reflectivity revealed that the Si films were grown in an amorphous state with an atomically flat surface. The a-Si films exhibited lithium alloying and de-alloying reactions, with a large irreversible capacity during the first cycle. The irreversible capacity was derived from the formation of a solid electrolyte interphase (SEI) along with an incompletely de-alloyed Li-Si phase, as confirmed by ex situ TEM and X-ray photoelectron spectroscopy observations. The discharge and charge capacities of the Si films gradually decreased in the subsequent cycles, despite the fact that no further SEI formation or cracking of the Si layer occurred. Scanning electron microscopy observations combined with energy-dispersive X-ray spectroscopy revealed the miniaturization of the a-Si film in the surface region to generate domains measuring less than a few hundred nanometers. These results suggest that delamination and miniaturization of the a-Si nanodomains from the electrode surface are partly responsible for degradation of the a-Si anode.</jats:p>

    Abstract

    Enhancing the understanding of fast lithium intercalation on cathode surfaces modified by oxides is crucial for the development of electrode materials that offer high‐power and long‐life operation. Herein, lithium transfer is elucidated by directly observing the structural changes within the cathode, through the interface, and into the electrolyte using in situ neutron reflectometry (NR). Two films are studied—a Li2ZrO3‐modified and an unmodified LiCoO2 film—and it is found that the modified film exhibits a superior rate capability. In situ NR studies indicate that the surface modification facilitates the formation of a dense cathode–electrolyte interphase (CEI), primarily composed of inorganic species. In contrast, the unmodified surface is covered by a relatively sparse and electrolyte‐impregnated CEI. These structural observations suggest that lithium desolvation during intercalation primarily occurs on the CEI and LiCoO2 surfaces for the modified and unmodified films, respectively. Fast desolvation of lithium on the CEI may contribute to the superior rate capability of the surface‐modified cathodes. This suggests a mechanism of fast intercalation achieved by surface modification of low ionically conductive oxides. Simultaneous chemical composition and morphological information is a powerful way to elucidate the dynamics at cathode/liquid electrolyte interfaces suitable for high‐power operation.
