The implementation of silicon (Si) in practical lithium ion battery electrodes has been hindered due to its large volume change and consequent structural and interfacial instabilities. Coating nanostructured Si with a second phase (e.g., carbon (C)) represents a very promising strategy for dealing with these critical issues facing Si-based electrodes. In this review article, we will outline recent advances in coating Si with engineered C matrices. By exemplifying hollow core-shell, core-hollow shell, and core-shell structured Si-C hybrid nanomaterials, we aim to highlight the importance of managing voids in designing such Si-C hybrid electrodes, and provide some scientific insights into the development of advanced Si-based anodes for next-generation lithium ion batteries.
