<P>PROBLEM TO BE SOLVED: To provide an evaluation method of a paste for lithium secondary battery which allows for shortening of the development time of a battery, and to provide a manufacturing method of a lithium secondary battery. <P>SOLUTION: While focusing on the carbon network in a positive electrode paste having a significant impact on the final battery characteristics, the characteristics of a lithium secondary battery are predicted based on the ratio of the viscosity of the positive electrode paste in a low shear region and the viscosity in a high shear region that represents the state of the carbon network, thus shortening the lead time of cell development while minimizing the development cost. <P>COPYRIGHT: (C)2013,JPO&INPIT |
