1. A power storage device, comprising:
- a stack having positive electrodes and negative electrodes stacked on top of each other with electrolytes interposed in-between and in which a positioning hole is formed, the positioning hole penetrating the stack in a stacking direction in which the positive electrodes, the negative electrodes, and the electrolytes are stacked;
a positioning member that is inserted into the positioning hole; and
a terminal portion that is formed at an end of the positioning member in an inserting direction in which the positioning member is inserted into the positioning hole, whereinthe terminal portion is provided with an electric wire that is connected to the positive electrode or the negative electrode of the stack.

Abstract
A power storage device has a stack including positive electrodes and negative electrodes that are stacked on top of each other with electrolytes interposed in-between. A positioning member is inserted into a positioning hole that is formed in the stack so as to penetrate the stack in the stacking direction. A terminal portion is formed at an end of the positioning member in the inserting direction.

15. A method for manufacturing a power storage device that has components constituting a stack, each component having a positioning hole, into which a positioning member is to be inserted, the method comprising:
-
fitting a lowermost current collector, which has only a negative electrode provided on one side of the lowermost current collector, to the positioning member; fitting current collectors and electrolytes alternately to the positioning member so that the current collectors and the electrolytes are stacked up on the side of the negative electrode of the lowermost current collector, each of the current collectors having a positive electrode provided on one side of the current collector and a negative electrode provided on the other side of the current collector; fitting an uppermost current collector, which has only a positive electrode provided on one side of the uppermost current collector, to the positioning member from the side of the positive electrode so that the positive electrode is placed on the electrolyte; connecting the uppermost current collector and the positive electrode terminal; and connecting the lowermost current collector and the negative electrode terminal, wherein the terminal portion is provided with an electric wire that is connected to the positive electrode or the negative electrode of the stack. - View Dependent Claims (16, 17, 18)
