TY  - JOUR
AB - Threedimensional dandelionshape TiO2/Multilayer graphene compound (TiO2/MLG) composed of TiO2(B) fibrils andanatase pappi structures has been synthesized as potential anode material for Li storage. Electronmicroscopy indicatesthat the composite contains triphase boundaries between anatase, TiO2(B) and graphene, which are responsible for theenhancement of energy storage and the decrease of electrode polarization. Cyclic voltammetric investigations indicatethat both Li+ insertion and pseudocapacitance contribute to charge storage. Ultrahigh specific capacities of 243 and 182mAh g1 have been obtained at 0.1 and 1 A g1, respectively. Moreover, the excellent capacity retention can reach 99.6%after 100 cycles with almost 100% coulombic efficiency at 0.1 A g1. The importance of the triphase boundary in enhancingthe storage of charge and transport of Li+ is demonstrated.
