Abstract

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.
