Recent Progress in SiC Nanostructures as Anode Materials for Lithium-Ion Batteries

Large volume variation during charge/discharge of silicon (Si) nanostructures applied as the anode electrodes for high energy lithium-ion batteries (LIBs) has been considered as the most critical problem, which inhibits their commercial applications. Searching for the alternative high-performance anodes for LIBs has been emphasized. Silicon carbide (SiC) nanomaterials, a wide bandgap semiconductor with excellent mechanical properties, have been investigated as the anode electrode materials even as the active materials, protective layers, or inactive buffer stuffs. In this mini review, we briefly summarize the synthesis of SiC nanostructures, the application of SiC/C anode materials, and SiC/Si composite anodes in LIBs.
