Abstract: The invention relates to lithium ion battery, more particularly to a lithium nickel cobalt manganese oxide (Li(Ni0.8Co0.1Mn0.1)O2) composite material, including lithium nickel cobalt manganese oxide and a hydrophobic material coated on the surface of lithium nickel cobalt manganese oxide. The hydrophobic material coated on the surface of lithium nickel cobalt manganese oxide is insoluble in water, so that the lithium nickel cobalt manganese oxide composite material solves the problem that the batteries using conventional lithium nickel cobalt manganese oxide materials easily absorb water. A method for preparing the lithium nickel cobalt manganese oxide composite material is also disclosed.

Abstract: An electrochemical method and apparatus for high-amperage electrical energy storage features a high-temperature, all-liquid chemistry. The reaction products created during charging remain part of the electrodes during storage for discharge on demand. In a simultaneous ambipolar electrodeposition cell, a reaction compound is electrolyzed to effect transfer from an external power source; the electrode elements are electrodissolved during discharge.

Abstract: The invention provides improved electrodes for electrolytic cells operating with molten salt electrolytes. Nonconsumable iridium-based anodes of the invention facilitate the release of gaseous oxygen from oxide-containing melts, for example in the electro-chemical production of liquid or gaseous reactive metals from oxides. Cathode substrates of the invention are constructed of a tungsten-based alloy and enable deposition of an overlying liquid-metal cathode. Incorporation of the anode and cathode substrate of the invention into molten-oxide cells establishes a novel method for electrolytic extraction of titanium and other reactive metals.

Abstract: The present invention relates to a dimensionally stable oxygen-evolving anode for use in an electrolytic cell for the production of aluminium. The anode comprises of a container made from an alloy comprising aluminium and at least one metal more noble than aluminium; a fluid bath in the bottom of the container having the ability to dissolve aluminium, said fluid having a density that is higher than the density of molten aluminium at the operating temperature of the cell, a pool of molten aluminium floating on top of the fluid bath in the bottom of the container; a refractory layer arranged on the inner sidewalls of the container at least in the area of the pool of molten aluminium, said refractory layer protecting the molten aluminium from contacting the inner sidewalls of the container.

Abstract: Solid battery components are provided. A block copolymeric electrolyte is non-crosslinked and non-glassy through the entire range of typical battery service temperatures, that is, through the entire range of at least from about 0° C. to about 70° C. The chains of which the copolymer is made each include at least one ionically-conductive block and at least one second block immiscible with the ionically-conductive block. The chains form an amorphous association and are arranged in an ordered nanostructure including a continuous matrix of amorphous ionically-conductive domains and amorphous second domains that are immiscible with the ionically-conductive domains. A compound is provided that has a formula of LixMyNzO2. M and N are each metal atoms or a main group elements, and x, y and z are each numbers from about 0 to about 1. y and z are chosen such that a formal charge on the MyNz portion of the compound is (4-x). In certain embodiments, these compounds are used in the cathodes of rechargeable batteries.
