摘要：

Highly stable solutions of 1,3-dioxolane (DN) with LiClO4 or LiAsF6 may be prepared by the use of tertiary amine additives. Very high Li-cycling efficiency is obtained with stabilized LiAsF6/DN solutions. These electrolytes can be further improved by addition of alkyl carbonates as cosolvents. The correlation between Li-cycling efficiency and Li-surface chemistry in these systems was investigated using surface sensitive Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and X-ray microanalysis techniques.
