Abstract
A negative-electrode active material is provided, the negative-electrode active material including: a lamellar polysilane having a structure in which multiple six-membered rings constituted of a silicon atom are disposed one after another, and expressed by a compositional formula, (SiH), as a basic skeleton; and the negative-electrode active material containing copper in an amount of from 0.01 to 50% by mass. To contain copper results in upgrading electron conductivity. Consequently, an electric storage apparatus using the negative-electrode active material for one of the negative electrodes has upgraded rate characteristic, and also has augmented charged and discharged capacities.
