Abstract: Six electrolytes were investigated for lithium metal battery applications.  The electrolytes were composed of combinations of four different salts (LiPF6, LiB(C2O4)2, LiI and LiN(SO2CF3)2) and three different solvents (PC, DME, and 1,3-Dioxolane).  All six electrolytes had conductivities >3 mS/cm at temperatures from –20 oC to 40 oC. Electrochemical Impedance Spectroscopy (EIS) and linear polarization, both at room temperature and low temperature (-8 oC), provided congruent results. The LiI based electrolyte had the lowest film resistance, while the 0.7 M LiB(C2O4)2-PC:DME (1:1) had the highest impedance. The presence of 1,3-Dioxolane in electrolytes provided lower impedance with LiB(C2O4)2 but higher resistance with LiPF6 based electrolytes. NMR analysis of electrolytes after thermal abuse indicate that LiN(SO2CF3)2 based electrolytes are the most thermally stable.  SEM analysis suggests that surface modification and impedance changes are correlated.

Remarks: 第一作者

虽然是一小paper，但这是我第一篇第一作者的文章，来得不易。我在澳洲做了一年访问学者，有好几篇二三作者的文章。本以为来到美国后文章会更多，结果发现美国的教授都是终身教授，发表文章极其谨慎。有些博士到毕业也很难有一篇。三年了，这是第一篇第一作者的，弥足珍贵！！！希望借Chem8的春风，在自己接下来的两年里，再有一篇或两篇一作，便满足了。
