A covalently tethered polyoxometalate (POM)–pyrene hybrid (Py–SiW11) is utilized for the noncovalent func-tionalization of single-walled carbon nanotubes (SWNTs). The resulting SWNTs/Py–SiW11 nanocomposite shows that both SiW11 and pyrene moieties could interact with SWNTs without causing any chemical decomposition. When used as anode material in lithium-ion batteries, the SWNTs/Py–SiW11 nanocomposite exhibits higher discharge capacities, and better rate capacity and cycling stability than the individual components.
