摘要： A method for producing and recovering a carboxylic acid in an electrolysis cell. The electrolysis cell is a multi-compartment electrolysis cell. The multi-compartment electrolysis cell includes an anodic compartment, a cathodic compartment, and a solid alkali ion transporting membrane (such as a NaSICON membrane). An anolyte is added to the anodic compartment. The anolyte comprises an alkali salt of a carboxylic acid, a first solvent, and a second solvent. The alkali salt of the carboxylic acid is partitioned into the first solvent. The anolyte is then electrolyzed to produce a carboxylic acid, wherein the produced carboxylic acid is partitioned into the second solvent. The second solvent may then be separated from the first solvent and the produced carboxylic acid may be recovered from the second solvent. The first solvent may be water and the second solvent may be an organic solvent.

摘要： An electrochemical cell having a composite alkali ion-conductive electrolyte membrane. Generally, the cell includes a catholyte compartment and an anolyte compartment that are separated by the composite alkali ion-conductive electrolyte membrane. The composite electrolyte membrane includes a layer of alkali ion-conductive material and one or more layers of alkali intercalation compound which is chemically stable upon exposure to a chemically reactive anolyte solution or catholyte solution thereby protecting the layer of alkali ion-conductive material from unwanted chemical reaction. The layer of alkali intercalation compound conducts alkali ions. The cell may operate and protect the alkali ion-conductive material under conditions that would be adverse to the material if the intercalation compound were not present. The composite membrane may include a cation conductor layer having additional capability to protect the composite electrolyte membrane from adverse conditions.

摘要： Ammonia is synthesized using electrochemical and non-electrochemical reactions. The electrochemical reactions occur in an electrolytic cell having a lithium ion conductive membrane that divides the electrochemical cell into an anolyte compartment and a catholyte compartment. The catholyte compartment includes a porous cathode closely associated with the lithium ion conductive membrane. The overall electrochemical reaction is: 6LiOH+N2→Li3N (s)+3H2O+3/2O2. The nitrogen may be produced by a nitrogen generator. The non-electrochemical reaction involves reacting lithium nitride with water and/or steam as follows: Li3N (s)+3H2O→3LiOH+NH3 (g). The ammonia is vented and collected. The lithium hydroxide is preferably recycled and introduced into the anolyte compartment. The electrolytic cell is shut down prior to reacting the lithium nitride with water. The cathode is preferably dried prior to start up of the electrolytic cell and electrolyzing Li+ and N2 at the cathode.

摘要： A hybrid battery with a sodium anode is designed for use at a range of temperatures where the sodium is solid and where the sodium is molten. When the battery is at colder temperatures or when the vehicle is idle and needs to be “started,” the anode will be solid sodium metal. At the same time, the battery is designed such that, once the electric vehicle has been “started” and operated for a short period of time, heat is directed to the battery to melt the solid sodium anode into a molten form. In other words, the hybrid battery operates under temperature conditions where the sodium is solid and under temperature conditions where the sodium is molten.

摘要： The present invention provides a secondary cell having a negative electrode compartment (15) and a positive electrode compartment (25), which are separated by an alkali ion conductive electrolyte membrane (40). An alkali metal negative electrode (20) disposed in the negative electrode compartment (15) oxidizes to release alkali ions as the cell discharges and reduces the alkali ions to alkali metal during recharge. The positive electrode compartment (25) includes a positive electrode (30) contacting a positive electrode solution (35) that includes an alkali metal compound and a metal halide. The alkali metal compound can be selected from an alkali halide and an alkali pseudo-halide. During discharge, the metal ion reduces to form metal plating on the positive electrode. As the cell charges, the metal plating oxidizes to strip the metal plating to form metal halide or pseudo halide or corresponding metal complex.

The first electrolyte (134) includes a solvent (154) which is non-reactive with the metal, and a salt bearing an alkali ion that may be conducted through the separator (120), wherein the salt is at least partially soluble in the solvent (120). A second electrolyte (138) is also used. The second electrolyte (138) contacts the second electrode (108).
