Abstract
A lithium polymer battery comprising an internal sheath, reinforcement members, and an external sheath and a method for manufacturing the same are provided. The lithium polymer battery comprises a pouch-type internal sheath with an electrode assembly positioned therein and a protective circuit module that is attached to the surface thereof to control the charging and discharging processes of the electrode assembly. The battery further comprises reinforcement members that couple with surfaces of the internal sheath and an external sheath for integrally enclosing the internal sheath and the reinforcement members. The external sheath may comprise a tube, a thermally contractible tube, or a melted resin.
Claims16
A battery, comprising:
- an internal sheath;
- an electrode assembly disposed in the internal sheath;
- a reinforcement member coupled with an outer surface of the internal sheath;
- and
- an external sheath coupled with the internal sheath and the reinforcement member,
- wherein a length of the reinforcement member is greater than a length of the electrode assembly, a length of the external sheath is greater than the length of the electrode assembly, or both the length of the reinforcement member and the length of the external sheath are greater than the length of the electrode assembly, and
- wherein the external sheath comprises a tube comprising a first side and a second side, the first side and the second side being open ends of the tube exposing the internal sheath.
