<P>PROBLEM TO BE SOLVED: To provide a positive active material having high charge discharge characteristics and to provide a nonaqueous electrolyte battery using the positive active material. <P>SOLUTION: A positive mix layer 2B contains the positive active material. In the positive active material, an absorption edge peak appearing in the vicinity of 530 eV at oxygen K absorption edge in X-ray absorption spectrum at the oxygen K absorption edge measured in an X-ray absorption fine structure (XAFS) analytical method shows certain behavior. By using this positive active material, reaction on the interface in a charged state is suppressed to enhance battery characteristics. <P>COPYRIGHT: (C)2008,JPO&INPIT |
