  "textContent": "A power storage device includes: a positive electrode that contains manganese dioxide; a negative electrode that contains zinc; a positive electrolyte in contact with the positive electrode; a negative electrolyte in contact with the negative electrode; and an anion exchange membrane that separates the positive electrode and the positive electrolyte from the negative electrode and the negative electrolyte. The anion exchange membrane has a zinc ion permeation rate of less than 15.6×10-6 [mol/cm2/24 hrs] and a membrane resistance of less than 12.3 [Ω·cm2].",
