Abstract
A power storage device cell is configured to include a capacitor positive electrode, a lithium positive electrode, and a common negative electrode in which electrode layers are formed on a collector foil in which penetration holes are formed, and such that the capacitor positive electrode and the lithium positive electrode are directly connected; each of the electrode layers of the common negative electrode is formed of a carbon-based material in which graphite particles and hard carbon particles are mixed, and the proportion of the hard carbon particles in the carbon-based material is from 5% by weight to 70% by weight.
