Abstract

Abstract : TiO2 @C nanospheres could exhibit a discharge capacity of 286.5 mA h g −1 at 100 mA g −1 after 200 cycles. Abstract : TiO2 @C nanospheres are synthesized through annealing a mixture of tetrabutyl titanate and oleic acid, as the titanium and carbon source, respectively. The as-synthesized TiO2 @C with higher carbon content presents a superior specific capacity (286.5 mA h g −1 at 100 mA g −1 after 200 cycles) and higher rate performance (148 mA h g −1 at 500 mA g −1 ), when tested as the anode material for lithium ion batteries. The as-synthesized TiO2 @C nanospheres are promising anode materials for next-generation LIBs.
