<P>PROBLEM TO BE SOLVED: To provide a power storage device that includes a solid electrolyte which is stable against moisture in atmosphere and has an increased concentration of Ag serving as a carrier ion, and that decreases interface resistance between a negative electrode and the solid electrolyte. <P>SOLUTION: A power storage device includes: a solid ion electrolyte layer in which at least one of Li, Cs, Rb, K, Ba, Sr, Ca, Na, Mg, Al, Cu, Hg, Au and Ag serves as a conductive ion; and a pair of electrodes sandwiching the solid ion electrolyte layer therebetween. At least one of the pair of electrodes is an electrode comprising the same metal element as the conductive ion of the solid electrolyte layer, and the metal electrode and the solid ion electrolyte layer are electrochemically joined to each other. <P>COPYRIGHT: (C)2012,JPO&INPIT |
