  • Electrochemical composition and associated technology
    Patent number: 8815116
    Abstract: A composition including a first material and a metal or a metal oxide component for use in an electrochemical redox reaction is described. The first material is represented by a general formula M1xM2yXO4, wherein M1 represents an alkali metal element; M2 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 above metal elements and alloys, wherein the two materials include different metal elements. Moreover, the first material and the metal or the metal oxide component are co-crystallized or physically combined, and the metal or the metal oxide component takes less than about 30% of the composition.
