Patent ID: 8029926

Claim:
A rechargeable battery, comprising: a bare cell comprising an electrode assembly arranged in a can and a cap assembly coupled with an opening arranged at an end portion of the can; a protective circuit module; a positive temperature coefficient device comprising an integrally formed first conductive section contacting one electrode of the bare cell, an integrally formed second conductive section contacting the protective circuit module, a positive temperature coefficient body arranged between and contacting the first conductive section and the second conductive section, and a cover member covering at least a portion of a surface of the positive temperature coefficient body, wherein the second conductive section is formed separate from the first conductive section; and molding resin arranged in a space between the protective circuit module and the bare cell, wherein the cover member prevents the molding resin from directly contacting a portion of the positive temperature coefficient body, wherein the cover member comprises a movable damping member, wherein the first conductive section contacts a portion of a first surface of the positive temperature coefficient body, wherein the second conductive section contacts a portion of a second surface of the positive temperature coefficient body, which is opposite the first surface of the positive temperature coefficient body, and is arranged opposite to the first conductive section, wherein the second surface faces the bare cell, wherein the cover member covers an entire first surface of the positive temperature coefficient body, the entire first surface facing the protective circuit module, and wherein another portion of the positive temperature coefficient body makes direct contact with the molding resin.
