Mesoporous single crystals Li4Ti5O12 grown on rGO as high-rate anode materials for lithium-ion batteries

Abstract

Mesoporous single crystals Li₄Ti₅O₁₂ grown on reduced graphene oxide (MSCs-LTO–rGO) nanohybrids have been synthesized by a simple hydrothermal reaction of TiO₂/rGO and LiOH with subsequent annealing in Ar at 600 °C, which exhibited high specific capacity (171 mA h g⁻¹) with much improved rate capability (132 mA h g⁻¹ at 40 C) and intriguing cycling stability (85% capacity retention after 2000 cycles).
