A nanocomposite of multiwalled carbon nanotubes (MWCNTs) anchored with SnS2 nanosheets (NS) (SnS2 NS@MWCNTs coaxial nanocables) has been synthesized through a simple solution-based method at room temperature. The synthetic mechanism of these intriguing nanocomposites is proposed as electrostatic attraction between tin ions and MWCNTs, followed by the nucleation and two-dimensional growth of SnS2. The as-synthesized SnS2 NS@MWCNTs coaxial nanocables have been applied as anode materials for lithium-ion batteries, which show better lithium storage performance compared to pure SnS2 nanosheets and MWCNTs. The combination of MWCNTs that can hinder the agglomeration and enhance electronic conductivity of the active materials might be responsible for the enhanced cyclic performance.
