| titleOfInvention | Conducting materials for high quality secondary battery and secondary batteries using them |
| abstract | The present invention relates to a conductive material for positive and negative electrodes of a high-performance secondary battery and a secondary battery using the same, which is prepared by colloidal dispersion and freeze-dried iron oxide (γ-ferrite) having an average particle diameter of 20 to 80 nm and / or After the nickel oxide fine particles are used as the basic catalyst, they are reduced in a reducing atmosphere at 400 to 700 ° C., and carbon and monoxide are used as the source gas, and then mixed with hydrogen in the catalyst surface of the mobile and / or fixed bed to 640 to 700. Highly crystalline multilayer carbon nanotubes prepared by gas phase decomposition at 占 폚 are used as the conductive material.n n n Unlike the conventional carbon black, the conductive material of the present invention has high electrical conductivity due to high crystallinity, has a small oxygen-containing function, maintains the current and voltage distribution of the electrode plate uniformly, and suppresses deterioration of the battery due to electrolyte decomposition. Therefore, it exhibits superior cycle stability compared to the conventional secondary battery using carbon black as a conductive material, and at the same time has excellent processability when making an electrode mixture, there is an effect of mass production of a high performance secondary battery. |
