Abstract
An electrolyte salt is shown herein for use in lithium/thionyl chloride primary cells that is provided to minimize the start-up delay otherwise encountered after too long a storage period or storage at too high a temperature. The salt is a reaction product produced by refluxing lithium triflate with either aluminum chloride or lithium tetrachloraluminate or a mixture of thereof dissolved in thionyl chloride.
Claims21
An electrochemical cell having an anode, a non-aqueous oxyhalide electrolyte and an electrolyte salt, and a cathode, comprising the addition to the oxyhalide of an electrolyte salt that contains at least a partially substituted product that results- from reacting a chloride selected from the group consisting of aluminum chloride and lithium aluminum chloride with lithium triflate.
