Abstract

Abstract : Core–shell type TiO2 @carbon nanosheets were constructed which exhibit excellent cyclability (385 mA h g −1 after 2000 cycles) as an anode for Li-ion batteries. Abstract : TiO2 @carbon with a nanosheet morphology and core–shell structure was constructed by self-assembly/carbonization of P123, CTAB and exfoliated titanate nanosheets. The obtained composite possesses an ultrathin structure (∼5.5 nm) and exhibits high capacity (549 mA h g −1 ) and excellent cyclability (385 mA h g −1 after 2000 cycles at 4.6 A g −1 ) as an anode for Li-ion batteries.
