For the Li{sub 9}V{sub 3}(P{sub 2}O{sub 7}){sub 3}(PO{sub 4}){sub 2} insertion electrode system with a multiple-electron reaction, the over-lithiated phase Li{sub x}V{sub 3}(P{sub 2}O{sub 7}){sub 3}(PO{sub 4}){sub 2} with 99) and Li{sub 9−y}Ag{sub y}V{sub 3}(P{sub 2}O{sub 7}){sub 3}(PO{sub 4}){sub 2} (0<1) systems are prepared. • The crystal structures and electronic properties are clarified. • In Li{sub x}V{sub 3}(P{sub 2}O{sub 7}){sub 3}(PO{sub 4}){sub 2}, the over-inserted Li4 ion resides in between the Li1 sites. • A linear chain of Li exists with the Li–Li distance of 3.40 Å parallel to the c-axis. • In Li–Ag system, the electron hopping and the electrostatic potential are reduced.
