摘要 以CuSO4.5H2O和NH4VO3为原料,采用水热法制备了Cu3V2O7(OH)2.2H2O纳米线。利用XRD、FE-SEM、TEM和HRTEM对样品的结构和表面形貌进行了表征,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纳米线电极具有较高的开路电压和较大的放电容量。 Using CuSO4 · 5H2O and NH4VO3 as raw materials, Cu3V2O7 (OH)2 · 2H2O nanowires are fabricated by a simple and facile bydrothermal process. The structure and morphologies of the as-synthesized Cu3 V2O7(OH)2 · 2H2O nanowires are characterized By XRD, FE-SEM, TEM and HRTEM. Electrochemical measurements reveal that the Cu3V2O7 (OH)2 · 2 H2O nanowires electrode exhibit a high open circuit voltage and a high discharge capacity.
