Abstract: A method of preparing a metal-carbon composite of a core-shell structure through simultaneous vaporization, in which a metal particle constitutes a core and carbon constitutes a shell, with the metal-carbon composite prepared in the form of powder and supported on a supporter, and a metal-carbon composite of a core-shell structure prepared by the same. In these methods, the metal-carbon composite of the core-shell structure is prepared through simultaneous vaporization of metal and carbon precursors and does not require separate post-processing. Further, in the metal-carbon composite of the core-shell structure prepared by these methods, a carbon shell covers a portion or the entirety of a surface of a metal core, whereby the metal particles can be prevented from suffering agglomeration, separation or corrosion when subjected to harsh process conditions at high temperatures for long durations under strong acid and alkali conditions, thereby providing high performance and high durability.
Abstract: The invention generally relates to methods of selectively removing lithium from various liquids, methods of producing high purity lithium carbonate, methods of producing high purity lithium hydroxide, and methods of regenerating resin.
Abstract: Methods and apparatus for the production of low sodium lithium carbonate and lithium chloride from a brine concentrated to about 6.0 wt % lithium are disclosed. Methods and apparatus for direct recovery of technical grade lithium chloride from the concentrated brine are also disclosed.

Abstract: The invention relates to an ionically conductive material, to its preparation and to its uses.
The material includes at least one ionic compound in solution in an aprotic solvent, chosen from the compounds (1/mM)+[(ZY)2N]−, (1/mM)+[(ZY)3C]− and (1/mM)+[(ZY)2CQ]−, in which Y denotes SO2 or POZ,
Q denotes —H, —COZ or Z, each substituent Z independently denotes a fluorine atom or an optionally perfluorinated organic group which optionally contains at least one polymerizable functional group, at least one of the substituents Z denoting a fluorine atom, and M denotes a cation.
Application to electrochemical generators, supercapacities, to the doping of polymers and to electrochromic devices.
