PROBLEM TO BE SOLVED: To provide a power storage device having adequate high-temperature resistance.SOLUTION: A power storage device comprises: a positive electrode 11; a negative electrode 12 facing the positive electrode 11; and inorganic particles each having a metal ion-absorbing group on the surface. The positive electrode 11 includes: a positive electrode base 111; and a positive electrode active material layer 112 superposed on the positive electrode base 111 and disposed to face the negative electrode 12. The negative electrode 12 includes: a negative electrode base 121; and a negative electrode active material layer 122 superposed on the negative electrode base 121, and disposed to face the positive electrode 11. The power storage device has an inorganic layer 8 including the inorganic particles and disposed between the positive electrode base 111 and the negative electrode base 121. The power storage device further comprises a separator base 4 between the positive electrode base 111 and the negative electrode base 121. The inorganic layer 8 is arranged to be put on any one face of the separator base 4. Alternatively, the power storage device does not have the inorganic layer 8; the inorganic particles are included in at least one of the positive electrode active material layer 112, the separator base 4 and the negative electrode active material layer 122.SELECTED DRAWING: Figure 2 |
