Electrode assembly for flexible rechargeable battery and flexible rechargeable battery including the same

An electrode assembly for a rechargeable battery, the electrode assembly comprising:

• a first electrode comprising a first coating part and a first uncoated region at at least one side of the first coating part, wherein a portion of the first uncoated region having a width less than that of other portions of the first electrode defines a first electrode tab;
• a second electrode comprising a second coating part and a second uncoated region at at least one side of the second coating part, wherein a portion of the second uncoated region having a width less than that of other portions of the second electrode defines a second electrode tab;
• a separator between the first electrode and the second electrode;
• and
• at least one of a first stress buffering part on at least a partial region of the first electrode tab and a second stress buffering part on at least a partial region of the second electrode tab,
• wherein the at least one of the first stress buffering part and the second stress buffering part is configured as a film comprising an ethylene propylene copolymer, a hydrogenated hydrocarbon polymer, and polyethylene.
