    Abstract: It has now been discovered that reduction in the coulombic efficiency of metal halogen cells can be minimized if the microporous separator employed in such cells is selected from one which is preferably wet by the aqueous electrolyte and is not wet substantially by the cathodic halogen.

    Abstract: An electrochemical cell is described which contains, in a sealed configuration, an anode having a zinc anode-active material, a cathode having a halogen compound cathode-active material, a liquid electrolyte having a gas space above it, and an auxiliary electrode. The auxiliary electrode is made of a carbon-containing hydrophobic material, is adapted to carry a cathodic potential, and is positioned in the cell so as to be partially located in the liquid electrolyte and partially located in the gas space. A method of retarding pressure build-up in the cell also is described. The method involves converting hydrogen gas which is generated in the cell and builds up in the gas space to its ionic state via the formation of an ionic compound and dissolving the compound in the liquid electrolyte by creating a cathodic potential at the auxiliary electrode.

    Abstract: Basically, the present invention is predicated on the discovery that zeolites that have a high silica to alumina ratio, e.g., a ratio of 20 and above, pore diameters of greater than about 5.0.ANG., and which have substantially no active acid sites, i.e., zeolites which are non-reactive toward olefin isomerization and oligomerization, are especially useful in substantially separating linear olefins and paraffins from hydrocarbon mixtures containing at least linear and branched aliphatic hydrocarbons and optionally containing aromatic and other hydrocarbons.

    Abstract: In one embodiment of the present invention, there is provided an electrochemical cell having a metal bromine couple. The cell includes an electrode structure on which to deposit the metal of the couple and a counterelectrode at which to generate bromine. A microporous membrane separates the electrode and counterelectrode. Importantly, the aqueous electrolyte comprises an aqueous metal bromide solution containing a water soluble bromine complexing agent capable of forming a water immiscible complex with bromine and an additive capable of decreasing the wettability of the microporous separators employed in such cells by such water immiscible bromine complexes.

    Abstract: The coulombic efficiency of aqueous zinc bromine batteries can be increased if, in addition to the bromide ions required to be present in the electrolyte to charge the cell to rated capacity, chloride ions are added to the electrolyte in amounts sufficient to reduce the amount of free bromine present in the electrolyte during operation of the cell.
