Reduced graphene oxide (rGO)-wrapped SnO2@TiO2 nanotubes (NTs) anodes exhibit superior rate capability and cycle retention due to stable solid electrolyte interphase (SEI) layer and enhanced electrical conductivity through TiO2 and rGO-coated layer.

In this work, the sulfonated reduced graphene oxide (SRGO) was synthesized and proposed as an enhanced anode material for lithium ion battery (LIB). The result shows that the SRGO has an improved battery performance (i.e., ∼341.7 mAh/g and ∼190.6 mAh/g corresponds to SRGO and RGO at the 100th cycle with a current density of 200 mA/g) and superior cycling stability compared with pristine reduced graphene oxide (RGO). These are attributed to the improved specific surface area (448.35 m2/g) and conductivity (2.5 × 10-4 S/m). Further, the SRGO exhibits good rate capability and excellent energy density at various current densities ranging from 50 mAh/g to 2000 mAh/g, suggesting that SRGO could be a promising anode material for high capacity LIB.
