摘　　要：以钼酸氨为钼源,葡萄糖为还原剂,在醋酸体系中通过简单的一锅水热还原法制备了锂离子电池用纳米MoO_(2)负极材料。通过XRD、FT-IR、SEM和恒流充放电等测试分析了材料的组成、形貌和电化学性能。结果表明,水热温度150℃,时间12 h时制备的材料表现出较高的可逆比容量和优异的循环稳定性。以100 mA/g电流密度充放电,50次循环后可逆比容量保持在约900 mAh/g。Nano-Molybdenum dioxide(MoO_(2))anode material for lithium-ion battery was prepared by a simple one-pot hydrothermal reductive method using ammonium molybdate as precursor and glucose as reducing agent in acetic acid solution.The composition,morphology and electrochemical performance of MoO_(2)were characterized by X-ray diffraction(XRD),fourier transform infrared spectra(FT-IR),scanning electron microscopy(SEM)and constant current discharge/charge tests.The results indicated that the MoO_(2)nanoparticles synthesized at the temperature of 150℃for 12 h exhibited a high initial specific capacity and excellent cycling stability.A high reversible specific capacity of about 900 mAh/g could be remained after 50 cycles at a current density of 100 mA/g.
