Patent ID: 8709637

Claim:
An electrode assembly comprising; a plurality of separator members formed by winding a separator on the basis of a central separator member, wherein the central separator member is a predeterminated portion of the separator; and a plurality of electrode members positioned between each of the separator members wherein the plurality of electrode members are attached to opposing sides of the separator member; wherein the separator including the plurality of separator members and the central separator member is one of the plurality of separator members and wherein the plurality of electrode members comprise a first and second electrode member having inner and outer surfaces wherein the inner surfaces of the first and second electrode members are attached to the central separator member, and wherein both opposite ends of the central separator member are curved in opposite directions, respectively, wherein the plurality of electrodes members comprises an electrode collector, respectively, wherein each of the electrode collectors is physically divided from each other on the winding separator so that no electrode member is attached to two portions of the winding separator immediately adjacent both sides of the central separator member and wherein the portions of the winding separator having no electrode member attached thereto cover the outer surface of the first and second electrode members.
