Abstract

Flexible and binder-free graphene-TiO 2 paper was prepared by a simple route. A unique 3-D nano-structure was achieved with nano-sized TiO 2 intercalated between graphene layers as pillars, significantly increasing the Li-ion insertion/extraction rate. At a current rate of 2 Ag -1, the specific capacity can reach 122 mAhg -1 after 100 charge/discharge cycles. More remarkably, the flexible graphene/TiO 2 hybrid paper shows an excellent stability when the rates decrease from 4 Ag -1 back to 200 mAg -1 with the retained capacity of 175 mAhg -1.
