An aqueous rechargeable lithium battery based on LiV₃O ₈ and Li[Ni_1/3Co_1/3Mn_1/3]O ₂

The electrochemical performance of a rechargeable lithium battery using LiV₃O₈ as negative electrode, Li[Ni_1/3Co _1/3Mn_1/3]O₂ as positive electrode material, and a 2 M Li₂SO₄ aqueous solution as electrolyte are discussed. The crystalline LiV₃O₈ was prepared by melting a mixture of Li₂CO₃ and V₂O₅ in an appropriate molar ratio at 680°C and by cooling it slowly down to room temperature. The crystal structures of all samples were determined by XRD using a Bruker Analytical X-Ray Systems with CuK_α radiation source filtered by a Ni thin plate. The electrochemical measurements were performed at ambient temperature. The results suggest that this type of ARLB might be a good energy storage and conversion systems as the average discharge voltage of the ARLB is 0.83 V, the cell can be repeatedly charged and discharged.
