In the present work, SnCo-CMK nanocomposite was successfully synthesized for the first time via a simple nanocasting route by using mesoporous carbon as nano-reactor. The nanocomposite was then characterized by means of X-ray diffraction (XRD), thermogravimetric analysis (TG), N-2 adsorption-desorption, scanning and transmission electron microscopy (SEM/TEM) respectively. Furthermore, the SnCo-CMK nanocomposite exhibited large reversible capacities, excellent cycling stability and enhanced rate capability when employed as an anode material for lithium-ion batteries. A large reversible capacity of 562 mA h g(-1) was obtained after 60 cycles at a current density of 0.1 A g(-1) which is attributed to the structure of 'meso-nano' SnCo-CMK composite. This unique structure ensures the intimate contact between CMK and SnCo nanoparticles, buffers the large volume expansion and prevents the aggregation of the SnCo nanoparticles during cycling, leading to the excellent cycling stability and enhanced rate capability.
