    Li4NiTeO6 as a positive electrode for Li-ion batteries

    Get PDF
    Layered Li4NiTeO6 was shown to reversibly release/uptake B2 lithium ions per formula unit with fair capacity retention upon long cycling. The Li electrochemical reactivitymechanism differs from that of Li2MO3 and is rooted in the Ni4+/Ni2+ redox couple, that takes place at a higher potential than conventional LiNi1�xMnxO2 compounds.We explain this in terms of inductive effect due to Te6+ ions (or the TeO6 6� moiet
