Laminate film packaged storage device and fabricating method thereof

A laminate film packaged storage device, comprising:

• a fundamental cell formed by disposing a positive electrode layer and a negative electrode layer on respective opposite surfaces of a separator;
• a first structure in which a first laminate film having a first opening and a first collector rubber are disposed with a first metal terminal plate interposed therebetween, and a surface of the first collector rubber is disposed so as to come into contact with a surface of the positive electrode layer of the fundamental cell;
• and
• a second structure in which a second laminate film having a second opening and a second collector rubber are disposed with a second metal terminal plate interposed therebetween, and a surface of the second collector rubber is disposed so as to come into contact with a surface of the negative electrode layer of the fundamental cell,
• wherein the fundamental cell is sealed in a package cell that is made of the first structure and the second structure by fusion bonding the first laminate film and the second laminate film at peripheries thereof,
• wherein first and second openings are formed on respective surfaces of the fundamental cell opposite to each other, and
• wherein the first and second metal terminal plates are partially exposed at the first and second openings, respectively.
