Inventor(s) include Kwon, Soonho; Cha, Myeonggeun; Park, Sungbin; Kim, Mingyu; Cho, Woohyung; Kim, Ki Hwan; Koh, Jongkwan; Park, Eun Kyoung; Kang, Joon Koo; Song, Intaek; Yang, Heemyeong; and Choi, Hyunju.
The application for the patent was published on May 30, under issue no. 22/2025.
According to the abstract released by the Intellectual Property India: "The present invention relates to an electrode for a lithium secondary battery and a lithium secondary battery comprising same, wherein the electrode effectively suppresses heat generation or ignition, making it possible to provide a battery exhibiting excellent charge/discharge characteristics while having improved safety. The electrode for a lithium secondary battery comprises: a metal current collector; and an active material layer including an electrode active material and a conductive material and formed on the metal current collector. The active material layer further includes a conductive polymer that exhibits a peak in the band of 1350 to 1600 cm-1 when the Raman spectrum is analyzed and exhibits positive temperature coefficient (PTC) characteristics. When Raman image analysis is performed on a cross-section of the active material layer, at least 90% by weight of the conductive polymer is found to be distributed in an area extending to 10% of the thickness of the active material layer from the surface of the metal current collector."
The patent application was internationally filed on Nov. 03, 2023, under International application No.PCT/KR2023/017469.
