Original Abstract Submitted

A method of synthesizing a flexible and binder-free electrode material for lithium-ion batteries using multi-walled carbon nanotubes (MWCNTs) on copper (Cu) foil directly. The growth of MWCNTs is carried out by plasma-enhanced chemical vapor deposition (PECVD) using a sputter-coated chromium (Cr) barrier layer and a nickel (Ni) catalyst on Cu foil. The resultant electrode material can be used as a binder-free and flexible anode for lithium-ion batteries.
