Patent ID: 7879491

Claim:
A stacking type electrode assembly constructed in a cathode/separator/anode structure, wherein the electrode assembly comprises, at a predetermined region thereof, at least one through-hole, and a pair of holding members constructed in a male-female coupling type structure, wherein the pair of holding members is a male coupling member and a female coupling member, and is inserted through the through-hole inside a battery case, an outer surface of the female coupling member being brought into tight contact with the through-hole when the male coupling member is inserted into the female coupling member while the female coupling member having an outer diameter less than an inner diameter of the through-hole when the female coupling member is inserted through the through-hole, wherein the through-hole of the electrode assembly is constructed such that a through-hole part formed in separators has an inner diameter less than inner diameters of through-hole parts formed in cathodes and anodes.
