A Novel Composite Li 3 V 2 (PO 4 ) 3 ∥Li 2 NaV 2 (PO 4 ) 3 /C as Cathode Material for Li-Ion Batteries

Lingfang Li, Changling Fan, Jiaxing Yang

COMP-B has four pairs of redox peaks in CV curve matching up with four plateaus in the charge/discharge curves. We can conclude that most intercalation/deintercalation reactions occur at a potential of 3.8/3.7 V, which makes its working potential more stable than Li3V2(PO4)3. This enhancement of electrochemical performance could be attributed to the synergistic effect between monoclinic Li3V2(PO4)3 and rhombohedral Li2NaV2(PO4)3.
