| Popis: | Recently, the silicon-based materials have been in the spotlight as a promising next-generation anode for lithium ion batteries (LIBs) due to their high capacity compared to graphite-based materials. In this study, we propose a silicon monoxide (SiO) with dual layer composed of black titania (BT) and carbon as an anode material for high-performance LiBs. Attractively, BT and carbon coating on the surface of SiO reduces the volume expansion of active materials and side reaction between the electrode and electrolyte during the charging and discharging process, and provide high electrical and ionic conductivity. Finally, it is confirmed that the dual coating layer imparts SiO with improved cycling stability, high initial efficiency and fast Li+-de/insertion kinetics. |
