Abstract

As part of a search for chemically and electrochemically stable ambient temperature molten lithium salt systems, we have investigated the properties of solutions of LiAlCl4 with various second components. In this paper we review the factors which determine the ambient temperature conductivity and report results for two systems, one of which satisfies the stability requirements although failing to provide the high conductivities which are needed for a successful ambient temperature Li battery electrolyte. These ionic solutions appear to be very fragile liquids. Evidence is found for a mixing incompatibility of polarizable and nonpolarizable components of binary melts.
