NEGATIVE ELECTRODE, ELECTRICITY STORAGE DEVICE AND VEHICLE

摘要

The purpose of the present invention is to provide: a negative electrode wherein separation of an active material layer from a metal foil can be suppressed; an electricity storage device; and a vehicle. A negative electrode according to the present invention is provided with: a metal foil; and an active material layer which is on the surface of the metal foil and contains a plurality of active material particles for negative electrodes, said active material particles having a predetermined average particle diameter. The surface of the metal foil has a formation region on which the active material layer is positioned. The surface of the metal foil has a recessed portion in the formation region. Some of the active material particles are at least partially present in the recessed portion. The average distance between the centers of two adjacent active material particles, which are at least partially present in the recessed portion, is from 70% to 98% (inclusive) of the average particle diameter of the active material particles.
