nanoparticle (NP) doped fullerenol have been investigated. Ag NP doped
fullerenol is prepared using the electrostatic self-assembly method
followed by a pyrolysis process, and characterized by Fourier transformation
intermediate infrared (FT-IR), X-ray photoelectron spectroscopy (XPS),
transmission electron microscopy(TEM), galvanostatic charge/discharge
cycling, and cyclic voltammograms (CV). Experimental results indicate
that Ag NP doped fullerenol exhibits an initial discharge capacity
of 389 mAh·g–1 during galvanostatic charge/discharge
cycling, and maintains a discharge capacity of 283 mAh·g–1 at a current density of 50 mA·g–1 after 50 cycles. The doped product is a mixture of fullerenol and
Ag NPs, which distributes among the sample and acts as an electrical
conductor in the discharge/charge process. The discharge/charge mechanism
is a reversible formation of Lin(C60O10) and liberation of Li+ from this
Li metallized compound. It is therefore believed this material can
be used as an anode for lithium ion battery application.
