Revealing the size-dependent electrochemical Li-storage behaviors of SiO-based anodes
Silicon monoxide (SiO) is a potential high-capacity anode material for lithium-ion batteries. The complexity of the lithiation process for SiO and challenges in the characterization of the lithiated products are fundamental aspects that underpin the discovery of the reaction mechanisms.

| description | Silicon monoxide (SiO) is a potential high-capacity anode material for lithium-ion batteries. The complexity of the lithiation process for SiO and challenges in the characterization of the lithiated products are fundamental aspects that underpin the discovery of the reaction mechanisms. In this work, we investigate the size-dependent (micro- and submicro-) electrochemical behaviors of SiO electrodes in terms of the irreversibility/reversibility of electrochemical lithiation/delithiation, interfacial/bulk stability, and interplay between SiO and graphite particles in the blended electrode.
