Graphical abstract In situ-growth of 1T/2H-MoS 2 nanosheets on the CFC, ultra-small SnS 2 nanoparticles are anchored on the surface of MoS 2 nanosheets unifromly. When the SnS 2 /MoS 2 /CFC composites applied as a binder-free flexible anode, it exhibits excellent performances. A highly flexible full cell was fabricated, demonstrating remarkable flexibility and cycling stability. Highlights • In-situ growth SnS 2 /MoS 2 on CFC by a hydrothermal method and water bath process. • SnS 2 /MoS 2 shows a capacity of 1294 mA h g−1 at 0.1 A g−1 after 120 cycles. • The distribution of SnS 2 on 1T/2H-MoS 2 can enhance electrochemical properties. • A full cell is fabricated, showing high flexibility and electrochemical properties. Abstract Flexible lithium ion batteries are important for wearable electronic devices. Herein, 1T/2H phase MoS 2 nanosheets are grown on carbon fiber cloth, and the ultra-small SnS 2 nanoparticles are anchored in the surface of MoS 2 nanosheets uniformly. We fabricate the hierarchical nanostructures via a hydrothermal method then water bath process. During in-situ growth of 1T/2H phase MoS 2 , urea is used as the surfactant and NH4+ (produced by urea and ammonium molybdate tetrahydrate) is acted as insertion guest ions to stabilize 1T phase MoS 2. The synergistic effects between MoS 2 nanosheets and SnS 2 nanoparticles can improve structural stability of the electrode and significant enhance the transport of Li ions and electrons, thereby ameliorate the electrochemical properties. When applied as a binder-free, flexible Li-ion battery anode, it exhibits admirable cycling stability and excellent rate performance. Due to the presence of 1T phase MoS 2 and uniform distribution of ultra-small SnS 2 nanoparticles on MoS 2 nanosheets, the SnS 2 /MoS 2 /carbon fiber cloth composites maintain 1294 mA h g−1 when cycling at 100 mA g−1 after 120 cycles. A highly flexible battery based on SnS 2 /MoS 2 /carbon fiber cloth and LiCoO 2 is fabricated, demonstrating excellent mechanical flexibility and cycling stability. [ABSTRACT FROM AUTHOR]
