Li4NiTeO6 as a positive electrode for Li-ion batteries†

Résumé

Layered Li4 NiTeO6 was shown to reversibly release/uptake B2 lithium ions per formula unit with fair capacity retention upon long cycling. The Li electrochemical reactivity mechanism differs from that of Li 2MO3 and is rooted in the Ni 4+/Ni2+ redox couple, that takes place at a higher potential than conventional LiNi 1Àx MnxO2 compounds. We explain this in terms of inductive effect due to Te 6+ ions (or the TeO 66À moiety).
