Abstract:
A production method of a negative electrode active material containing a silicon compound (SiO x : 0.5≤x≤1.6) that contains Lithium includes: making a silicon compound into which the lithium has been inserted contact with a solution B containing a polycyclic aromatic compound or a derivative thereof or both thereof (here, the solution B contains one or more kinds selected from an ether-based solvent, a ketone-based solvent, an ester-based solvent, an alcohol-based solvent, and an amine-based solvent as a solvent); and making the silicon compound contact with a solution C (here, the solution C contains one or more kinds selected from an ether-based material, a ketone-based material, and an ester-based material as the solvent, and contains a compound having a quinoid structure in a molecule as a solute).

Claim (Index 25):
The production method of a negative electrode active material for nonaqueous electrolyte secondary batteries according to  claim 13 , wherein one or more kinds of naphthalene, anthracene, phenanthrene, naphthacene, pentacene, pyrene, picene, triphenylene, coronene, chrysene, and derivatives thereof are used as the polycyclic aromatic compound, and one or more kinds of biphenyl, terphenyl, and derivative thereof are used as the straight chain polyphenylene compound.
