标 题 :Carbon combustion synthesis of oxides

摘要:The present invention is generally directed to a novel, economic synthesis of oxide ceramic composites. Methods of the present invention, referred to as carbon combustion synthesis of oxides (CCSO), are a modification of self-propagating high-temperature synthesis (SHS) methods in which the heat needed for the synthesis is generated by combustion of carbon in oxygen rather than that of a pure metal. This enables a more economic production of the ceramic material and minimizes the presence of intermediate metal oxides in the product. The reactant mixture generally comprises at least one oxide precursor (e.g., a metal or non metal oxide, or super oxide, or nitride, or carbonate, or chloride, or oxalate, or halides) as a reactant, but no pure metal. Pure carbon in the form of graphite or soot is added to the reactant mixture to generate the desired heat (upon ignition). The mixture is placed in a reactor and exposed to gaseous oxygen. The high-temperature exothermic reaction between the carbon and oxygen generates a self-sustaining reaction in the form of a propagating temperature wave that causes a reaction among the reactants. The reaction proceeds rapidly following ignition, and the final product comprises simple and/or complex oxides of elements present in the oxide precursor(s). CCSO also enables synthesis of oxides that cannot be produced by conventional SHS, such as when the pure metal is pyrophoric (such as Li or La) or such as when it melts at room temperature (e.g., Ga) or such as the combustion heat of the metal is relatively low.

权利人:WESTAIM TECHNOLOGIES INC
摘要:A single calcination stage process for the synthesis of homogeneous crystalline lithium nickel cobalt dioxide from either a mechanical mixture of nickel and cobalt oxides, hydroxide or oxyhydroxide or a chemical precipitation of a homogeneous nickel cobalt hydroxide or cobalt nickel cobalt oxyhydroxide is provided. The reactants are calcined in the presence of lithium hydroxide and an alkali metal hydroxide under predetermined oxygen partial pressure and temperature conditions. The products of the process are characterized in having a lithium to transition metal ratio closely approximating to the desired theoretical value.

摘要:The present disclosure is generally directed to a single-step synthesis of nanostructured thin films by a chemical vapor and aerosol deposition (CVAD) process. The present disclosure is also directed to methods for controlling the morphology of the nanostructured thin films. The films can be used, for example, in lithium ion and/or sodium ion battery electrodes, solar cells and gas sensors.

标题:Synthesis of lithiated transition metal oxides
发明人：WOLSTENHOLME JACK; LI WU; CURRIE JOHN C; DUBOIS MAURICE
权利人:WESTAIM TECHNOLOGIES INC
摘要:A synthesis for lithiated transition metal oxide powders is provided which comprises reacting one or more transition metal compounds with a lithium compound, wherein the lithium compound is in a molten phase. The reaction mixture may contain additives, which act primarily to extend the temperature range of the molten phase of the lithium compound.

摘要:This invention relates to metal-doped lithium manganese oxide and methods of its production. In particular, it relates to stable lithium manganese oxide in monoclinic form, doped with one or more metal ion, the preferred dopants being one or both of aluminium and chromium. The method of the invention involves the synthesis of stable metal-doped lithium manganese oxide in monoclinic form by high temperature solid state reaction.

摘要:A process to deposit a conformal coating of manganese oxide nanocrystals within a high surface area connected pore structure of a carbon paper electrode. A two-step process is utilized. In the first step the carbon paper electrode is immersed in an alkaline manganese oxide solution to form a nanocrystal seed layer on the surface and within the pores of the carbon paper. In the second step the seeded carbon paper is immersed in an acidic manganese oxide solution. The result is a densely packed continuous conformal nanocrystal coating both on the surface of the carbon and deep within its pores. The carbon paper is highly suitable for use as an electrode in a supercapacitor.
