Abstract

In this study, NiO was synthesized via a facile method and coated on the surface of a TiO₂ anode material doped with rGO (reduced graphene oxide). TiO₂/NiO/rGO nanocomposite structures were synthesized by a two-step solid-state method, and their lithium storage capacity was investigated and compared with that of both as-prepared TiO₂/NiO and pure TiO₂. The coating over the TiO₂ surface helped to attain a higher capacity and cycle stability than that without it, even at high current rates. The TiO₂/NiO/rGO nanocomposites show excellent performance with an initial discharge capacity of up to 324 mAh/g between 0 and 3 V vs Li at 20 mA/g. Furthermore, at a high current density of 100 mA/g, the TiO₂/NiO/rGO nanocomposite still achieved a capacity of 245 mAh/g after 200 cycles. This excellent performance could be attributed to the stable framework and high electronic conductivity within the TiO₂/NiO/rGO nanocomposite.
