Lithium Intercalation of Carbon-Nanotube Electrodes

Abstract

High aligned multiwall nanotubes (MCNTs) have been obtained by catalytic decomposition of carbon-containing organic compounds by plasma-enhanced hot-filament chemical vapor deposition (PEHFCVD) on nickel substrates. Such a MCNT-based structure serves as a convenient material for studying the electrode process of lithium-ion intercalation. Lithium insertion electrochemical measurements were performed and charge/discharge capacities were determined. Results showed the MCNT arrays inserted and de-inserted lithium with considerable irreversible capacities. This may have resulted from the formation of acetone/alcohol insoluble films on MCNT arrays. Future studies should concentrate on the effects of MCNT-array conditions (e.g., opened or closed ends, nanotube size, length and density) on the intercalation irreversibilities.
