Abstract
- The monoclinic-type Li 3 V 2 (PO 4 ) 3 cathode material was synthesized via calcining amorphous Li 3 V 2 (PO 4 ) 3 obtained by chemical reduction and lithiation of V 2 O 5 using oxalic acid as reducer and lithium carbonate as lithium source in alcohol solution. The amorphous Li 3 V 2 (PO 4 ) 3 precursor was characterized by using TG–DSC and XPS. The results showed that the V 5+ was reduced to V 3+ by oxalic acid at ambient temperature and pressure. The prepared Li 3 V 2 (PO 4 ) 3 was characterized by XRD and SEM. The results indicated the Li 3 V 2 (PO 4 ) 3 powder had good crystallinity and mesoporous morphology with an average diameter of about 30 nm. The pure Li 3 V 2 (PO 4 ) 3 exhibits a stable discharge capacity of 130.08 mAh g −1 at 0.1 C (14 mA g −1 ).
