Background Developing new anode materials with high specific capacity for high-performance lithium (Li)-ion batteries is significant for meeting high energy density demand. Composites of graphene-wrapped titania (TiO2) nanoparticles (GTO) have been successfully synthesized via a facile method for anode material in Li-ion batteries. Results The as-prepared GTO composites exhibit remarkable electrochemical performance, including initial high specific capacity of 652.8 mAh g(-1) and outstanding cycling stability (198 mAh g(-1) after 300 cycles). Conclusions The outstanding performance is due to the positive effect of graphene, which acts both as electron conductor and volume buffer layer. This work further demonstrates that GTO composites could acts as a stable anode for reversible Li-ion batteries. (c) 2022 Society of Chemical Industry (SCI).
