Abstract: The present invention relates to a method for recovering indium in a high selectivity and a high efficiency from an indium-containing solution, dispersion or mixture such as seawater, industrial water, waste water, cooling water, a solution extracted from wastes of electronic products such as display panel, or the like.

Abstract: The present invention provides surface-modified silicon nanoparticles comprising a LixSiyOz top film and a carbon (C) coating layer on the surface of the nanoparticles by means of the addition of a lithium source and a carbon source during the manufacture of silicon nanoparticles or a post-treatment thereof. According to the present invention, the surface oxidation of the silicon nanoparticles, which would easily occur during a pulverization process, can be prevented. By using the silicon nanoparticles of which oxidation is prevented as a negative electrode material, problems related to decrease in capacity and electrolyte depletion resulting from an oxidized film can be mitigated. Thus, a deterioration in the properties of a lithium secondary battery can be prevented.
