Abstract
A metal tin-carbon composite having excellent properties required for various use applications, a method for producing the composite at low cost and in a simple manner, and use applications of a non-aqueous lithium secondary battery produced using the composite are provided. A metal tin-carbon composite comprising metal tin nanoparticles (B) contained in a sheet-like matrix (A) composed of carbon, wherein the metal tin-carbon composite contains the metal tin nanoparticle (B) having a particle size of a range of 0.2 nm to 5 nm and does not contain a coarse metal tin particle having a particle size of 1 μm or more, a preferable method for producing the composite using a specific precursor, an anode active material for a non-aqueous lithium secondary battery comprising the composite, a negative electrode for non-aqueous lithium secondary battery using the anode active material, and a non-aqueous lithium secondary battery.
