ChemInform Abstract
The cathode performance of Li3V2(PO4)3 and Li3(V1-xZrx)2 (PO4)3 with x = 0.05—0.02 is studied. TG/DTA results show two phase transitions for Li3V2(PO4)3 while the Zr-substituted phases exhibit no phase transition. Powder XRD and conductivity measurement confirm the stabilization of the high temp. phase at room temperature. The discharge capacity of the Zr-substituted phases is much larger than that of pure Li3V2(PO4)3.
