Silicon oxycarbide (SiOC) has recently regained attention in the field of Li-ion batteries, owing to its effectiveness as a host matrix for nanoscale anode materials alloying with Li. The SiOC matrix, itself providing a high Li-ion storage capacity of 600 mA h g −1, assists in buffering volumetric changes upon lithiation and largely suppresses the formation of an unstable solid-electrolyte
