Abstract

Lithium-based battery, a key component of various electronic devises including cellular phones, laptop computers, and digital cameras, is now expanding its applications to vehicles and other large-scale power systems due to the high energy density and energy efficiency. Imidazolium-based room temperature ionic liquids have received considerable interest as potential electrolytes for lithium batteries, due to their favorable properties such as wide electrochemical window, high ionic conductivity, non- flammability, and wide operating temperature range. Several ionic liquids containing a methyl ester group on the cations with a hope that the favorable interaction between the ester group and a lithium salt could improve various electrochemical properties of the resulting electrolytes such as lithium ion conduction are prepared. All the ionic liquids tested exhibited high thermal stabilities. The decompositions at lower temperatures were likely to be due to the decomposition of the ester group. This is an abstract of a paper presented at the AIChE Annual Meeting and Fall Showcase (Cincinnati, OH 10/30/2005-11/4/2005).
