Lithium Closoborane Electrolytes: III . Preparation and Characterization

Abstract

The lithium closoborane salts and were prepared from decaborane, purified, and dissolved in 1,2‐dimethoxyethane (DME)/1,3‐dioxolane mixtures. The solubility behavior is complex, as the salts are insoluble in either solvent alone, and concentrated solutions separate into two liquid phases upon dilution. Electrolyte resistivity measurements as a function of temperature and concentration are reported. These electrolytes have resistivities of approximately 150 Ω cm at room temperature and are quite stable, making them attractive candidates for applications in lithium cells.
