摘要： A method for improving the environmental stability of cathode materials used in lithium-based batteries. Most currently used cathode active materials are acutely sensitive to environmental conditions, e.g. leading to moisture and CO2 pickup, that cause problems for material handling especially during electrode preparation and to gassing during charge and discharge cycles. Binder materials used for making cathodes, such as PVDF and PTFE, are mixed with and/or coated on the cathode materials to improve the environmental sensitivity of the cathode materials.

摘要： A method for recovering base metal values from oxide ore is provided by the present disclosure. The ore includes a first metal selected from the group consisting at least one of iron and aluminum and a second metal selected from the group consisting of at least one of nickel, cobalt and copper. The method includes the steps of: contacting the oxide ore with hydrogen chloride gas to obtain chlorides of the first and second metals and subjecting at least the first and second metals to pyrohydrolysis at a predetermined temperature to decompose the chlorides of the first metal into oxides. The method also includes the step of mixing the oxides of the first metal and the chlorides of the second metal in an aqueous solution to dissolve the chlorides of the second metal and recovering the dissolved ions of the second metal from the aqueous solution.

摘要： A hydrometallurgical resin-in-leach (RIL) process for directly recovering nickel and/or cobalt. Simultaneous pulp leaching by adding an acid or base, dissolves the metals of interest with adsorption of the metals rendered soluble in on ionic exchange resin. Following elution of the changed resin, purification of nickel and cobalt present in the eluate can be recovered by conventional methods, such as precipitation, extraction by solvents and membranes. The regenerated resin is recirculated for further use.

摘要： An acidic aqueous electrolyte solution for production of a nickel cathode is provided which includes nickel ions, and 2,5-dimethyl-3-hexyne-2,5-diol. The 2,5- dimethyl -3-hexyne-2,5-diol may be present in the acidic aqueous electrolyte solution in an amount ranging from about 5 ppm to about 300 ppm. Also provided is a process for electrowinning or electrorefining a nickel cathode which includes providing an acidic aqueous electrolyte solution including nickel ions, and 2,5- dimethyl -3-hexyne-2,5-diol; and electrolytically depositing nickel to form a nickel cathode. Addition of 2,5- dimethyl -3-hexyne-2,5-diol results in a reduction of striations and other defects which may occur on the surface of cathodes made by electrowinning or electrorefining.

摘要： The invention relates to a process for the production of sintered porous bodies, to porous bodies produced correspondingly using the process, and to their use. With the solution according to the invention, sintered bodies which achieve improved properties, such as an increased surface area, deformability of the structures at room temperature or modification of the initial pore volume, are to be produced. To this end, at least one sintering-active powder which forms at least one intermetallic phase or mixed crystals is applied to the surface of a porous basic body. Heat treatment is to be carried out subsequently, in which intermetallic phases or mixed crystals which increase the specific surface area can be formed.

摘要： A composition for use with alloys including extra-fine nickel powder dispersed with a hydrophobic inorganic dispersant which is preferably high-purity fumed silica treated with hexamethyldisilazane. The composition prevents the agglomeration of the nickel powder, thereby preventing weaknesses in alloys, like steel for example, formed with the nickel powder. A method for making an alloy with the composition includes mixing the nickel powder with other metals and/or nonmetals and the hydrophobic fumed silica to form an alloy blend, pressing the alloy blend, and sintering the alloy blend.

摘要： The invention relates to a method for fabricating an open-porous molded body which is formed from nickel or iron and at least another element which form solid solutions or intermetallic phases as well as a molded body which is correspondingly fabricated, and the use thereof. During the fabrication it is proceeded then, such that a coating with a metallic powder forming solid solutions or intermetallic phases is deposited upon an open-porous body made of nickel or iron by means of an organic binder. Subsequent thereto, the open-porous body provided with the coating is brought into the desired shape with observing minimum bending radii, and subsequently the organic components are removed in a first thermal treatment step. By means of a second thermal treatment the open-porous molded body is sintered, and the solid solution or the intermetallic phase are formed.
