<P>PROBLEM TO BE SOLVED: To provide a negative electrode for a nonaqueous secondary battery which can be discharged with the current density of around several 10 A/g with respect to the negative electrode active material weight of which the electrode density is high, and of which the capacity based on the negative electrode active material weight is high for obtaining an extra high output device having an energy density of 100 Wh/L or more and output characteristics of 300 C or more since a demand level for high energy density and high output/high rate charging characteristics is high, and provide a nonaqueous secondary battery using it having the high energy density and the high output. <P>SOLUTION: In the negative electrode for the nonaqueous secondary battery formed mainly of an insoluble and an infusible base body which is a heat-treated material of an aromatic condensed polymer composed of carbon, hydrogen, and oxygen, and contains a polyacene-based skeletal structure wherein an atomic ratio of a hydrogen atom and a carbon atom is 0.60 to 0.05, this is the negative electrode for the nonaqueous secondary battery in which the average particle diameter of the insoluble and infusible base body is 2.0 μm or less and in which a lithium of 500 mAh/g or more based on the weight of the insoluble and infusible base body is carried in advance, and the nonaqueous secondary battery using it. <P>COPYRIGHT: (C)2008,JPO&INPIT |
