    摘要： The present invention relates to a catalyst for preparing a carbon nanotube having desired apparent density by controlling the adding amount of co-precipitating agent in the process of preparing a catalyst in order to obtain a catalyst having a minimized particle size. More specifically, this invention relates to a catalyst for preparing carbon nanotube having desired apparent density based upon the reverse-correlation between the amount of co-precipitating agent added in the process of preparing catalyst and the apparent density of catalyst. The carbon nanotube prepared by the catalyst having low apparent density shows excellent electrical conductivity and highly uniformed dispersion in the polymer/carbon nanotube composite.

    摘要： A method for grouping unit cells of a similar impedance spectrum uses pattern matching technology to optimize the performance of a battery pack made of primary or secondary batteries as the unit cells connected in series, in parallel or in combination of them. To make an optimal battery pack with unit cells of a different internal characteristic, the method includes measuring the impedance spectrum of the individual unit cell in a wide frequency region at the same temperature and in the same state of charge (SOC), digitizing the difference in impedance spectrum among the unit cells into a relative value using the pattern matching technology, and selecting unit cells of a most similar impedance spectrum (i.e., a smallest relative difference in impedance spectrum) to make a battery pack.
