  • An electrolyte electrochemical device includes an anodic material and an electrolyte, the electrolyte including an organosilicon solvent, a salt, and a hybrid additiving having a first and a second compound, the hybrid additive configured to form a solid electrolyte interphase film on the anodic material upon application of a potential to the electrochemical device.
  • A secondary zinc/oxygen electrochemical cell is described that uses a circulating aqueous inorganic oxyacid electrolyte and has an external load circuit or charging circuit in electronic communication with the anode and cathode, the circuit being completed by ionic interaction through an ionic separator between the catholyte and anolyte. The electrochemical cell of this invention provides a process for production of electricity and may be recharged by providing electrical energy from the external circuit.
  • Provided are electrochemical cells and electrolytes used to build such cells. The electrolytes include ion-supplying salts and fluorinated solvents capable of maintaining single phase solutions with the salts at between about -30.degree. C. to about 80.degree. C. The fluorinated solvents, such as fluorinated carbonates, fluorinated esters, and fluorinated esters, are less flammable than their non-fluorinated counterparts and increase safety characteristics of cells containing these solvents. The amount of fluorinated solvents in electrolytes may be between about 30% and 80% by weight not accounting weight of the salts. Fluorinated salts, such as fluoroalkyl-substituted LiPF.sub.6, fluoroalkyl-substituted LiBF.sub.4 salts, linear and cyclic imidemore » salts as well as methide salts including fluorinated alkyl groups, may be used due to their solubility in the fluorinated solvents. In some embodiments, the electrolyte may also include a flame retardant, such as a phosphazene or, more specifically, a cyclic phosphazene and/or one or more ionic liquids.« less
  • An electrochemical cell includes a high voltage cathode configured to operate at 1.5 volts or greater; an anode including Mg.sup.0; and an electrolyte including an ether solvent and a magnesium salt; wherein: a concentration of the magnesium salt in the ether is 1 M or greater.
  • This patent describes a non-aqueous, electrochemical cell having an active metal anode, a solid active cathode and a liquid electrolyte. It is characterized in that the electrolyte consists essentially of a low vapor pressure, liquid solvate-complex of sulfur dioxide and one or more alkali or alkaline earth metal salts soluble in the sulfur dioxide and also capable of forming a complex therewith, wherein the one or more salts consists essentially of a stoichiometric reaction product of a Lewis acid and a Lewis base, with the equivalent ratio of the one or more salts to SO{sub 2} in the liquid electrolytemore » ranging from 1:1 to 1:7, and wherein all of the one or more alkali or alkaline earth metal salts is complexed with the sulfur dioxide.« less
