Abstract

In this paper, the amorphous Bi4V2O11 is synthesized by a simple precipitation method at room temperature. The as-prepared Bi4V2O11 was characterized by using powder XRD, FTIR, SEM/EDX techniques. The amorphous Bi4V2O11 has been tested as a cathode material for lithium secondary battery for the first time. The observed results were compared with the reported crystalline Bi4V2O11 wherein amorphous Bi4V2O11 exhibits better specific capacity and capacity retention at the charging rate of C/5. The specific capacity of 104 mA h g(-1) for the first cycle and 101 mA h g(-1) for the second cycle was observed and thereby the capacity retention of about 98% indicates the good reversibility.
