Patent ID: 7976981

Claim:
A pouch-type lithium secondary battery comprising: an electrode assembly comprising: a first electrode plate and a first electrode tab attached to the first electrode plate, the first electrode tab having a first longitudinal axis and extending from the first electrode plate in a direction defined by the first longitudinal axis, a second electrode plate and a second electrode tab attached to the second electrode plate, the second electrode tab having a second longitudinal axis substantially parallel to the first longitudinal axis of the first electrode tab and extending from the second electrode plate in a direction defined by the second longitudinal axis, and a separator between the first electrode plate and the second electrode plate; and a pouch material comprising a first surface, a second surface, and a third surface, wherein the first surface and the second surface of the pouch material are folded together along a first fold to form an electrode assembly accommodating unit for accommodating the electrode assembly, and wherein the third surface of the pouch material wraps entirely around the electrode assembly accommodating unit at least once, the first fold extending in a direction substantially parallel to the direction in which the first electrode tab and the second electrode tab extend from the electrode assembly.
