ELECTRICAL STORAGE DEVICE AND METHOD FOR MAKING THE SAME

Abstract:

To provide an electrical storage device in which a positive electrode material and a negative electrode material are each impregnated with a different type of electrolytic solution and a method for making the same. An electrical storage device (1) includes a negative electrode (2) including an organic electrolytic solution (21), a positive electrode (3) including an aqueous electrolytic solution (31), and a solid electrolyte (4) disposed between the negative electrode (2) and the positive electrode (3). The negative electrode (2) is entirely sealed. The electrical storage device (1) includes a sealing member (5), which is provided at the periphery of the negative electrode (2) and seals the negative electrode (2). The solid electrolytes (4) form a pair including a sealing material and together with the sealing member (5) seal the negative electrode (2) so that the negative electrode (2) is disposed between the solid electrolytes (4).
