MUMBAI, India, Sept. 22 -- Intellectual Property India has published a patent application (202617078157 A) filed by Terawatt Technology K. K. on June 24, 2026, for Lithium Secondary Battery And Method For Manufacturing Lithium Secondary Battery.
Inventors include Kajikawa, Tetsushi; Oyama, Gosuke; and Ogata, Ken.
The application for the patent was published on September 18, 2026, under issue no. 38/2026.
Abstract: The present invention provides: a lithium secondary battery that achieves weight reduction, cost reduction, and an excellent capacity retention rate; and a method for manufacturing a lithium secondary battery. The present invention pertains to a lithium secondary battery including: a positive electrode; a separator; and a negative electrode including a negative electrode current collector and a negative electrode active material layer on the negative electrode current collector. The negative electrode current collector includes a resin layer and a metal layer provided on both surfaces of the resin layer. The negative electrode active material layer faces the positive electrode via the separator. The separator includes an adhesive layer on the negative electrode-side surface. A peel strength x at 25°C between the resin layer and the metal layer is 0.05 N/cm or greater. A peel strength y at 25°C between the negative electrode active material layer and the separator satisfies x y.
