<P>PROBLEM TO BE SOLVED: To provide a composition including a first material and a metal or a metal oxide component for use in an electrochemical redox reaction. <P>SOLUTION: The first material is represented by a general formula M<SP>1</SP><SB>x</SB>M<SP>2</SP><SB>y</SB>XO<SB>4</SB>, wherein M<SP>1</SP>represents an alkali metal element; M<SP>2</SP>represents an transition metal element; X represents phosphorus; O represents oxygen; x is from 0.6 to 1.4; and y is from 0.6 to 1.4. Further, the metal or the metal oxide component includes at least two materials selected from the group consisting of transition metal elements, semimetal elements, group IIA elements, group IIIA elements, group IVA elements, alloys thereof and oxides of the metal elements and alloys, wherein the two materials include different metal elements. <P>COPYRIGHT: (C)2011,JPO&INPIT |
