摘要
制备了双草酸硼酸锂(LiBOB)与乙酰胺(C_2H_5NO)形成的离子液体。采用电导率法和循环伏安法对其电化学性质进行研究,结果显示,配比α(LiBOB):n(C_2H_5NO)=1:5,1:6,1:7的样品室温电导率随着温度的升高而增加,其电化学稳定电位窗口约为3.2 V。由此可以看出,该离子液体具有较宽的电化学窗口,在Li离子电池和超级电容器中具有很好的应用前景。
Novel binary molten salt electrolytes based on LiBOB and C_2H_5NO were prepared.The electrochemical properties were evaluated by ac impedance spectroscopy and cyclic voltammertry,respectively.The conductivity of LiBOB-C2H5NO electrolyte at molar ratio of 1:5,1:6 and 1:7 increase with the increase of temperature,And the electrochemical windowwas about 3.2 V.From this we can see that the ionioc liquide with wide electrochemical wondow.In lithium ion butteries and super capacitors in a good prospect.
