Abstract: An electrode that includes a polymer layer showing a positive temperature coefficient (PTC) effect and an oxidation potential, which are controlled according to objectives. The electrode does not affect or can rather improve, in a normal state, performance and operation of a secondary battery by exhibiting excellent electrical properties, such as low resistance, and can ensure stability in an abnormal state. Also provided are uses of the electrode.

Abstract: A copolymer that exhibits a positive temperature coefficient (PTC) effect and an oxidation potential which are controlled according to objectives. Such a conductive copolymer cannot affect or can rather improve, in a normal state, performance and operation of a secondary battery by exhibiting excellent electrical properties such as low resistance, and can form, in an abnormal state, a current collector for an electrode, an electrode, and a secondary battery including same. Also provided is a use of the copolymer.

Abstract: A current collector that includes a current collector body and a polymer layer formed on the current collector body, wherein the polymer layer can include a conductive polymer and a conductive material. The current collector can exhibit excellent electrical properties, including low resistance, in a normal state, and can ensure stability through an increase in resistance, and the like, in an abnormal state. Also provided are uses of the current collector.

Abstract: An electrode current collector that includes a current collector body and a polymer layer formed on the current collector body, where the polymer layer includes a copolymer containing a first thiophene unit having a hydrocarbon group with 10 or more carbon atoms and a second thiophene unit having a hydrocarbon group with 9 or less carbon atoms, and the electrode current collector can exhibit excellent electrical characteristics, including low resistance, in a normal state in a secondary battery or the like, and can ensure stability through an increase in resistance in an abnormal state. Also provided are uses of the electrode current collector.

Abstract: A current collector and a use thereof is disclosed. The current collector is capable of forming an electrode, which does not affect performance and operation of a secondary battery by exhibiting, in a normal state, excellent electrical characteristics including low resistance, and can ensure stability by blocking, in an abnormal state, energization of an electrode assembly through resistance increase, and a use thereof. An electrode, an electrode assembly and a secondary battery comprising the current collector are also described.

Abstract: Disclosed is a current collector, and a method for using the current collector. The current collector is capable of forming an electrode, which does not affect performance and operation of a secondary battery by exhibiting, in a normal state, excellent electrical characteristics including low resistance, and can ensure stability by blocking, in an abnormal state, energization of an electrode assembly through resistance increase.
