The properties of the electrolyte include high conductivity, high Coulombic efficiency, and an electrochemical window that can exceed 3.5 V vs. Mg/Mg+2. The use of the electrolyte promotes the electrochemical deposition and dissolution of Mg without the use of any Grignard reagents, other organometallic materials, tetraphenyl borate, or tetrachloroaluminate derived anions. Other Mg-containing electrolyte systems that are expected to be suitable for use in secondary batteries are also described.Type: ApplicationFiled: March 14, 2013Publication date: September 26, 2013Applicant: PELLION TECHNOLOGIES, INC.Inventors: Robert Ellis Doe, George Hamilton Lane, Robert E.
