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.

Predoping method for negative electrode active material, manufacturing method for negative electrode, and manufacturing method for power storage device

A predoping method for a negative electrode active material to dope the negative electrode active material with lithium ions. The predoping method for a negative electrode active material includes: a predoping process and a post-doping modification process. In the predoping process, the negative electrode active material is doped with lithium ions, to thereby reduce a potential of the negative electrode active material relative to lithium metal. In the post-doping modification process, after the predoping process, reaction is caused between a reactive compound that is reactive with lithium ions and lithium ions doped into the negative electrode active material, to thereby increase the potential of the negative electrode active material relative to lithium metal. The potential of the negative electrode active material relative to lithium metal is 0.8 V or more at completion of the post-doping modification process.

Provided is a method for manufacturing an electrode material having a pressing step in which an irregularly shaped aggregate containing at least an active material is statically pressed in the presence of an alkali metal source and a solvent.
