MoS2 architectures supported on graphene foam/carbon nanotube hybrid films: highly integrated frameworks with ideal contact for superior lithium storage

Three-dimensional (3D) nanoworm-like MoS2 architectures have been successfully synthesized and directly supported on graphene foam/carbon nanotubes (GF/CNT) hybrid films. The sp(2)-hybridized GF/CNT films provide robust frameworks with an ideal contact for the nucleation and subsequent massive growth of the MoS2 architectures, while acting as an efficient current collector with a conductive contact for binder-free electrodes. The as-prepared hierarchical MoS2@GF/CNT electrode shows capacities of 1368 mA h g(-1) and 823 mA h g(-1) at current densities of 200 mA g(-1) and 5000 mA g(-1), and can retain 81.3% of the initial reversible capacity up to 120 cycles.
