Description |
Carbon materials of various types have been extensively used as negative electrode materials for rechargeable
Li-ion batteries because of their consistent performance and potentialities. High aspect ratio (>1000)
carbons such as carbon fibers and multiwalled carbon nanotubes (MWCNTs) of different dimensions have
been employed to fabricate free standing anode materials. Various characterization techniques such as
SEM, TEM, TGA, XRD, Raman spectroscopy, mercury intrusion porosimetry has been carried out to evaluate
the structure of the anode that was further correlated to its performance in Li-ion cell. MWCNTs
prepared under specified conditions not only exhibits high purity and crystallinity in structure but also
shows exceptional electrochemical behavior of increasing capacity with successive cycling. This is probably
due to the formation of a very constructive SEI with negligible charge transfer resistance as shown
by the Nyquist plots.
