<P>PROBLEM TO BE SOLVED: To provide a battery using a sulfide, capable of suppressing an increase in resistance at an interface between a collector and an electrode body and manufacturing costs. <P>SOLUTION: A battery includes: an electrode body having a positive electrode layer, a negative electrode layer, and an electrode body with an electrolyte layer arranged between the positive electrode layer and the negative electrode layer; a positive electrode collector arranged so that electrons can move between the positive electrode layer and the positive electrode collector; and a negative electrode collector arranged so that electrons can move between the negative electrode layer and the negative electrode collector. In the battery, the electrode body contains a material containing sulfur, the positive electrode collector and/or the negative electrode collector are a collector foil selected from a group consisting of a copper foil, a nickel foil, an iron foil, an aluminum foil, a copper-nickel alloy foil, and a copper-iron alloy foil, and a layer containing one or more elements selected from the group consisting of Cr, Ti, W, C, Ta, Au, Pt, Mn, and Mo is arranged between the collector foil and the electrode body. <P>COPYRIGHT: (C)2012,JPO&INPIT |
