High Pressure Lithium Intercalation into Catalytic Carbon Nanotubes

Abstract
The successful intercalation of lithium into catalytic carbon nanotubes under high pressure conditions is reported. The compounds obtained have Li contents as high as 1–2 Li/ lC and repeat distances along the c-axis 3.69–4. 11 Å, preserving the tubular structure of the nanotubes. XRD, Infrared spectroscopy and 7Li NMR investigations are performed to characterize the compounds obtained.
