MUMBAI, India, June 30 -- Intellectual Property India has published a patent application (202617053500 A) filed by Lg Energy Solution, Ltd. on April 27, 2026, for Electrode Composite Film, Manufacturing Method Thereof, And Dry Electrode And Lithium Secondary Battery Comprising Same.
Inventors include Lee, Ki Seok; Lee, Nam Jeong; Shin, Dong Mok; Jang, Eun Ji; Chung, Koo Seung; Lee, Ho Chan; Jeong, Yoon Gyeong; and Ryu, Ho Hyeon.
The application for the patent was published on June 26, 2026, under issue no. 26/2026.
Abstract: The present invention relates to a composite film comprising: an electrode active material including an active material core and a carbon coating layer disposed on the surface of the core; and a fiberized binder, wherein the conductive path connectivity index (CPCI) defined by factors such as the cohesion of the binder, the volume cumulative average particle diameter D50 of the electrode active material, and the thickness of the carbon coating layer in the electrode active material is 0.09-0.45. The dry electrode has excellent resistance characteristics due to excellent conductive path connectivity, even when not including a conductive material. By including the dry electrode, it is possible to provide a lithium secondary battery having excellent output and excellent energy density on the basis of excellent resistance characteristics.
