摘要
以CuSO4.5H2O和NH4VO3为原料,采用沉淀法制备了Cu3V2O7(OH)2.2H2O纳米片。利用XRD、FE-SEM、TG对样品的结构和形貌进行了表征,并对其作为锂电池正极材料的电化学行为进行了研究。电化学性能测试表明:Cu3V2O7(OH)2.2H2O纳米片具有较高的放电容量和良好的高温放电性能,是一类性能优良的锂电池正极材料。
Using CuSO4 ·5H2O and NH4VO3 as raw materials, Cu3V207 （OH）2·2H2O nanoflakes were fabricated by a simple and facile chemical precipitation. The structure and morphologies of the as-synthesized Cu3 V2O7 （OH）2· 2H2O nanoflakes were characterized by XRD, FE-SEM and TG. Electrochemical measurements revealed that the Cu3 V2O7 （OH）2· 2H2O nanoflakes exhibited high discharge capacities and excellent high-temperature dischargeability and were thus promising cathode candidates in the field of primary lithium batteries.
