20140044969 | COLLOIDAL DISPERSION OF A MATERIAL IN A DIVIDED STATE AND CONSISTING OF METAL CHALCOGENIDE IN AN AQUEOUS MEDIUM, MATERIAL IN A DIVIDED STATE, AND USES THEREOF - A colloidal dispersion of a metal chalcogenide material in divided state in an aqueous liquid phase selected from the group consisting of aqueous solutions and solutions including a mixture of water and at least one solvent that is miscible with water, wherein the carbon element of the material is present in a proportion of less than 2.5 wt. % as determined by elemental analysis, the concentration of the material in the colloidal dispersion is more than 40 g/l, and the colloidal dispersion has a charge potential value which is negative and the absolute value of which is higher than 20 mV. | 02-13-2014 |
20110297889 | METHOD FOR MANUFACTURING A COMPOSITE MATERIAL OF SnO2 AND CARBON NANOTUBES AND/OR CARBON NANOFIBERS, MATERIAL OBTAINED BY THE METHOD, AND LITHIUM BATTERY ELECTRODE COMPRISING SAID MATERIAL - A method for manufacturing a composite material including tin oxide particles and a fibrillar carbon material, including synthesising tin hydroxide particles obtained from a tin salt by precipitation/nucleation in a water-alcohol medium, in the presence of the fibrillar carbon material and an acid, the fibrillar carbon material being nanotubes, carbon nanofibres, or a mixture of the two. The method can be used for the production of negative electrodes for lithium-ion batteries. | 12-08-2011 |
