摘要：
A predoping method for a negative electrode active material to dope the negative electrode active material with lithium ions using an electrolyte solution that includes lithium ions. The electrolyte solution includes at least one type of additive having a reduction potential higher than a reduction potential of a solvent contained in the electrolyte solution.
