<P>PROBLEM TO BE SOLVED: To provide an ionic conductive material having higher ionic conductivity, and a nonacqueous electrolytic secondary battery having the ionic conductive material. <P>SOLUTION: The ionic conductive material contains a polymeric acid lithium salt. According to the polymeric acid lithium salt, the equivalent weight of a lithium contained in the polymeric acid lithium salt is ≤185 g/Li-mol, and the minimum of pKa is calculated at ≤4.5 when both ends of a repeated structure of the polymeric acid lithium salt are replaced with methyl groups and lithium cations of the polymeric acid lithium salt are replaced with protons. <P>COPYRIGHT: (C)2008,JPO&INPIT |
