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： This invention relates to a filtering device for diesel engines based on metal foams. In order to achieve high filtration efficiency with low pressure drop using deep bed filtration metal foams, a radial flow concept is used based on a 'porosity gradient'. The foams can also be coated with catalytically active material to enhance soot oxidation (regeneration), as well as reduction of other exhaust gas pollutants (CO, hydrocarbons, nitrogen oxides). This may be accomplished by using non-uniform amounts of catalytic materials within the filter depending on the targeted application. An additional secondary filter segment (13) may be placed within the metal support of the main filter segment (8). The metallic diaphragms (11, 12, 16) at the entrance and exit of the external shell (1 ) are designed in such a way as to allow the flow to be divided between the main (8) and the secondary (13) filter segments according to the respective flow resistances. The filter can be designed in such a way as to ensure very high filtration efficiency when clean and ensure a non-blocking behavior in case the soot loading in the filter reaches extremely high values due to various reasons such as prolonged low temperature operation.
