    摘要: The present invention is to provide a negative electrode active material for nonaqueous secondary batteries, which is useful in production of nonaqueous secondary batteries that have low initial irreversible capacity and little gas generation due to decomposition of nonaqueous electrolytic solution, and have excellent charge/discharge cycle stability. The present invention relates to a negative electrode active material for nonaqueous secondary batteries, which comprises an active material (A) capable of occluding and releasing lithium ions and an organic compound (B), wherein the organic compound (B) is hardly soluble in a nonaqueous electrolytic solution, has a π-conjugated structure, and has an electric conductivity at 25°C of 0.1 S/cm or less.
