Graphene oxide/lithium titanate composite with binder-free as high capacity anode material for lithium-ion batteries

The Li4Ti5O12 particles are well dispersed among graphene oxide (GO) nanosheets and the two dimensional (2D) wrinkled paper-like structure GO extends in all directions like a stretched network. Moreover, the LGC-10% presents a very high reversible Li-storage specific capacity of 201 mAh g−1 at 0.5C (1C = 175 mAh g−1), which is higher than the capacity of LTO (163 mAh g−1 at 0.5C).226
