摘要: A SnS2@CNT nanocomposite as a high performance sodium-ion battery anode material is prepared via facile sintering route. Benefiting from the conductivity and strong mechanical properties of CNTs, with unique nanostructure 2D SnS2 sheets cross-linked by 1D delivers reversible capacity 758 mA h g−1 at 100 an excellent cyclability retention 87% over 300 cycles. More impressively, 445 can be obtained current density 5 g−1, demonstrating superior rate capability.
