摘要： An electrochemical cell (210) having a composite alkali ion-conductive electrolyte membrane (215). Generally, the cell (210) includes a catholyte compartment (214) and an anolyte compartment (212) that are separated by the composite alkali ion-conductive electrolyte membrane (215). The composite electrolyte membrane (215) includes a layer of alkali ion-conductive material (216) and one or more layers of alkali intercalation compound (222) which is chemically stable upon exposure to a chemically reactive anolyte solution or catholyte solution thereby protecting the layer of alkali ion-conductive material (216) from unwanted chemical reaction. The layer of alkali intercalation compound (222) conducts alkali ions. The cell (210) may operate and protect the alkali ion-conductive material (216) under conditions that would be adverse to the material if the intercalation compound were not present. The composite membrane (215) may include a cation conductor layer having additional capability to protect the composite electrolyte membrane (215) from adverse conditions.

摘要： A method for converting carboxylic acids (including carboxylic acids derived from biomass) into hydrocarbons. The produced hydrocarbons will generally have at least two oxygen containing substituents (or other substituents). In one example of application, the electrolysis converts alkali salts of carboxylic acids into diols which can then be used as solvents or be dehydrated to produce dienes, which can then be used to produce elastic polymeric materials. This process allows custom synthesis of high value chemicals from renewable feed stocks such as carboxylic acids derived from biomass.

摘要： A method for removing nitrogen from natural gas includes contacting substantially dry natural gas that contains unwanted nitrogen with lithium metal. The nitrogen reacts with lithium to form lithium nitride, which is recovered for further processing, and pipeline quality natural gas. The natural gas may optionally contain other chemical species that may be reduced by lithium, such as carbon dioxide, hydrogen sulfide, and small amounts of water. These lithium reducible species may be removed from the natural gas concurrently with the removal of nitrogen. The lithium nitride is subjected to an electrochemical process to regenerate lithium metal. In an alternative embodiment, lithium nitride is reacted with sulfur to form lithium sulfide and nitrogen. The lithium sulfide is subjected to an electrochemical process to regenerate lithium metal and sulfur. The electrochemical processes are advantageously performed in an electrolytic cell containing a lithium ion selective membrane separator.

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.
