三氧化钼—一种新型有机系钠离子储能器件负极材料
Molybdenum Trioxide:A New Type Negative Electrode Material for Electric Energy Storage Devices Using Na+-based Organic Electrolytes
摘要
Abstract
Owing to the shortage of lithium resources,we investigated the sodium-ion storage device using MoO3 as the negative electrode materials.MoO3 was prepared through a simple method and characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM) and transmission electron microscopy(TEM).MoO3 was used as the negative electrode materials for electric energy storage devices using Na +-based organic electrolytes.The charge storage mechanism at the MoO3 negative electrode was investigated by cyclic voltammetry and galvanostatic charge-discharge tests.A new type of electric energy storage devices was constructed with MoO3 as negative materials and activated carbon (or graphite) as positive materials.The electrochemical properties were studied in 1 mol/L NaPFr-propylene carbonate (PC).The MoO3/AC and MoO3/graphite devices owns the voltage ranges of 0 ～3.2 V and 0 ～ 3.5 V,energy densities of 31.6 Wh/kg and 53 Wh/kg,respectively.The long-cycling stabilities of both devices are superior to the AC/AC symmetric capacitor obviously.This kind of energy storage devices would be a good substitute for lithium-ion batteries.关键词
