SnS nanoparticles anchored on Ti3C2 nanosheets matrix via electrostatic attraction method as novel anode for lithium ion batteries

The innovative and reliable anode materials based on tin (II) sulfide materials have been prepared for lithium ion battery applications, in which SnS nanoparticles were uniformly anchored on Ti3C2 nanosheets matrix. A facile electrostatic attraction method was used to modify Ti3C2 nanosheets to improve the attractive force for SnS nanoparticles. The microscopic morphology, crystalline features and microstructure of SnS/PDDA-Ti3C2 composite materials were evaluated by various measurement such as X-ray diffraction (XRD), field emission scanning electron microscope (FESEM), X-ray photoelectron spectroscopy (XPS) and high-resolution transmission electron microscope (HRTEM). This composite anode exhibits enhanced lithium-ion storage performance compare with SnS, the hybrid materials exhibits an impressive specific capacity of 646 mAh g−1 at the current density of 100 mA g−1 after 100 cycles and excellent rate capability of 535 mAh g−1 at the current density of 2000 mA g−1. These results indicate that the novel electrode material offers a potential prospect for high-performance energy storage.
