摘要

Provided are: metal tin-carbon composites having excellent properties required for various use applications; a production method for producing said composites at low cost and in a simple manner; and use applications of a non-aqueous lithium secondary battery produced using said composites. A metal tin-carbon composite which comprises a sheet-like matrix (A) composed of carbon and metal tin nanoparticles (B) included in the sheet-like matrix (A), said composite being characterized in that each of the metal tin nanoparticles (B) has a particle diameter ranging from 0.2 to 5 nm and coarse metal tin particles each having a particle diameter of 1 μm or more are not contained; a preferred method for producing said composite using a specific precursor; an anode active material for non-aqueous lithium secondary batteries, which comprises said composites; an anode for non-aqueous lithium secondary batteries, which is produced using said anode active material; and a non-aqueous lithium secondary battery.
