| Abstract: Cathode material LiVPO4Cl for lithium-ion rechargeable batteries was synthesized by one-step hydro-thermal method. The result of XRD measurement shows that LiVPO4Cl material has a triclinic crystal structure， P1 space group; the results of SEM and TEM indicate that the sample is mostly single-crystalline， stick-like material; and the results of charge/discharge testing and cyclic voltammetry measurement demonstrate that the charging plateau of LiVPO4Cl material maintains at 4.02 V and the discharging plateau at 3.86 V. After sufficient activation， the discharge capacity at 0.1C rate of the fortieth cycle of LiVPO4Cl material with relatively higher content of carbon reaches 101 mAh·g-1. |
