Carbon Nanotubes in Composites

We report direct growth of vertically aligned carbon nanotubes (VCNTs) on Cu foils using thermal chemical vapor deposition and present the feasibility of possible applications as anode materials in lithium ion batteries. The VCNTs were vertically standing on the Cu foils which were covered with catalytic iron and alumina buffer layers. The growth temperature was 725°C and acetylene under atmospheric pressure was used as a hydrocarbon source. The VCNT grown had mean diameter of 5.8 nm and showed electrical ohmic contact to Cu foils. Electrochemical properties of Li ion battery cell using VCNT anode were examined and high capacitance was observed.
