Patent ID: 7531267

Claim:
A process for preparing a carbon nanotube electrode,consisting: (1) preparing an electrode material consisting essentially of carbon nanotubes mixed with a binder selected from the group consisting of sulfur having an average particle size of 1 μm or less, metal nanoparticles having an average particle size of 1 μm or less and both of them; (2) preparing a pressed electrode material by first pressing the electrode material under a pressure from 1 to 500 atm or about 1.033 to about 516.615 kgf/cm 2 ; and (3) subsequently pressing under a pressure from 1 to 500 atm or about 1.033 to about 516.615 kgf/cm 2 , or heat-treating at a temperature in the range of the melting point of the sulfur or metal nanoparticles ±200° C. in inert gas atmosphere, or simultaneously pressing under the said pressure and heat-treating at the said temperature in inert gas atmosphere the previously pressed electrode material that is placed on a current collector so that the carbon nanotubes are bonded to each other and simultaneously bonded to the current collector, by the binder being bonded, deposited, or fused on the surfaces of the carbon nanotubes; wherein the binder has the effect of minimizing the internal resistance of the electrode.
