Carbon nanotubes have been attracting lots of attention from various fields of science and
technology because of their extraordinary physical and chemical properties owing to their intrinsic
nano-sized quasi one-dimensional nature. Up to now, various synthetic methods for producing
carbon nanotubes have been developed (e.g., arc discharge, laser vaporization and catalytic
chemical vapor deposition (CCVD)). The most common process is to synthesize carbon nanotubes
by CCVD method because this technique is very powerful for producing in a large scale and
controlling the number of stacking shells, by using iron nanoparticles dispersed on the substrate or
in the floating reactant system [1-3]. Noticeably, highly ordered structure and high purity carbon
nanotubes have been industrially produced in a semi-continuous system through the right
combination of CCVD method and the subsequent high-temperature heat treatment.
From the view point of application of CNT, at first, current usage of carbon nanotubes as one of
the most important component in lithium ion secondary batteries is shown. Mainly, the effectiveness
of adding carbon nanotubes to both cathode and anode electrodes on the performance of lithium ion
secondary batteries will be discussed[4]. Secondly, the industrial usages of carbon nanotubes as
multi-functional filler in polymeric composites will be described.
Finally, for successful developments of CNT’s, the safety of carbon nanotubes is an important
issue [5-9]. By sharing all information on risks [5-9] and benefits of the materials with all the
stakeholders, by the responsible productions and uses as the 21st century‘s leading materials, and
through designing the safe nanostructure of CNT’s, we are able to prove that carbon nanotubes are
the green and safe innovative materials,

Short CV of Dr. M.Endo
Morinobu Endo studied electrical engineering at Shinshu University in Nagano, Japan, and
obtained Ph.D. in Engineering in 1978 from Nagoya University. In his doctor thesis, he
developed the synthesis method of carbon nanotubes, and showed a tubular structure of carbon
for the first time in 1976. In 1990, he became a professor of the Department of Electrical
Engineering, Shinshu University. His present posts are a Distinguished Professor of Shinshu
University and the Director of Endo Special Laboratory at The Institute of Carbon Science and
Technology. His current interests are science and technology of nanocarbons such as carbon
nanotubes, the development of high-performance energy storage devices (e.g., lithium ion
battery, electric double layer capacitor, and fuel cell) and multifunctional composites for wide
range applications..
