Patent number: 11777135Abstract: 3-D magnesium voltaic cells have a magnesium anode coated on multiple opposing surfaces with a continuous protective/electrolyte layer that is ionically conductive and electronically insulating. The resulting protected 3-D magnesium anode is coated on multiple opposing surfaces with a continuous cathode layer that is electronically and ionically conductive, and includes a magnesium storage medium. Suitable magnesium anodes, in particular, magnesium foam anodes, can be made by pulsed galvanostatic deposition of magnesium on a copper substrate. The protective layer can be formed by electropolymerization of a suitable methylacrylate ester. The continuous cathode layer can be a slurry cathode having powders of an electronic conductor and a reversible magnesium storage component suspended in a magnesium electrolyte solution.Type: GrantFiled: May 14, 2020Date of Patent: October 3, 2023Assignees: Toyota Motor Engineering & Manufacturing North America, Inc., Toyota Jidosha Kabushiki KaishaInventors: Fuminori Mizuno, Rana Mohtadi, Oscar Tutusaus, Nikhilendra Singh, Timothy S.

Patent number: 10892523Abstract: An electrolyte composition has a fluoroalkylsulfonyl salt and water. The water is present, relative to the fluoroalkylsulfonyl salt, at a molar ratio within a range of 0.1:1 to 10:1, inclusive. This creates a “water-in-salt” in which individual water molecules are surrounded by salt rather than vice versa. Water contained in this environment is electrochemically stabilized relative to a bulk water. The electrolyte also has an organic carbonate present, relative to the fluoroalkylsulfonyl salt, at a molar ratio within a range of 0.1:1 to 50:1, inclusive. It has been discovered that inclusion of the organic carbonate further increases the electrochemical stability of the water within the “in-salt” environment.Type: GrantFiled: October 27, 2016Date of Patent: January 12, 2021Assignee: Toyota Motor Engineering & Manufacturing North America, Inc.Inventors: Kensuke Takechi, Ruidong Yang
