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.

AbstractA carbon nanotube triode using Helicon Plasma-enhanced CVD with electroplated NiCo catalyst has been successfully fabricated. Isolated NiCo based metal catalyst was deposited at the bottom of the cathode wells by electroplating methods to control the density of carbon nanotubes and also reduce the activation energy of its growth. Helicon Plasma-enhanced CVD (HPECVD) has been used to deposit nanotubes at 400°C. Vertically aligned carbon nanotubes were then grown selectively on the electroplated Ni catalyst. Field emission measurements were performed with a triode structure. At a cathode to anode gap of 1.1mm, the turn on voltage for the gate was 170V.
