Abstract
It is an assignment to provide the following: a negative-electrode material for electric storage device, a negative electrode for electric storage device, and an electric storage device, negative-electrode material, negative electrode and electric storage device in which SiOis used as a negative-electrode active material, which excel in the conductivity, and which can inhibit the discharge capacity from declining; as well as a vehicle having the electric storage device on-board. In the negative-electrode material for electric storage device, acetylene black is used as a conductive additive; and, when a sum of contents of SiO, graphite, conductive additive and a binder resin is taken as 100% by mass, the contents are made so as to be as follows: a content of a negative-electrode active material including the SiOand graphite is 70% by mass or more; the content of the SiOis from 17% by mass or more and 40% by mass or less; a sum of the contents of the conductive additive and binder resin is from 8% by mass or more to 20% by mass or less; and the content of the conductive additive is from 6% by mass or more to 12% by mass or less.
