PROBLEM TO BE SOLVED: To provide a power storage device capable of storing higher capacity.SOLUTION: Disclosed is a power storage device, comprising: a positive electrode containing a carbonaceous material having a layered structure capable of adsorbing/desorbing anions; a negative electrode containing a carbonaceous material capable of adsorbing/desorbing lithium ions; and an organic electrolyte containing lithium salt. The power storage device uses a carbonaceous material having a prescribed layered structure as the positive electrode, using a carbonaceous material adsorbing lithium ions in advance as the negative electrode, performing charging/discharging at a maximum charging/discharging voltage between a range of 5.0 V to 5.4 V so as to achieve higher capacity. |
