Title:
COPOLYMER
Document Type and Number:
WIPO Patent Application WO/2024/085691
Kind Code:
A1
Abstract:
The present specification discloses a copolymer and a use thereof. The copolymer may exhibit: a positive temperature coefficient (PTC) effect which is controlled according to the objective; and an oxidation potential. Such a conductive copolymer, in a normal state, exhibits excellent electrical properties such as low resistance, and thus does not affect the performance and operation of a secondary battery and rather, enhances that performance and operation, and ensures stability in an abnormal state. Thus, the copolymer can be used to form a current collector for an electrode, an electrode, and a secondary battery including same. The present specification also discloses a use of the copolymer.
