MUMBAI, India, Nov. 21 -- Intellectual Property India has published a patent application (202517097030 A) filed by Dai Nippon Printing Co. Ltd., Tokyo, on Oct. 8, for 'power storage device, electrode terminal unit, and exterior body set.'
Inventor(s) include Uriu, Toshibumi; Miyashiro, Kae; Kanazawa, Sayako; and Sasaki, Miho.
The application for the patent was published on Nov. 21, under issue no. 47/2025.
According to the abstract released by the Intellectual Property India: "A power storage device comprising an electrode body, an exterior body, and an electrode terminal. The exterior body seals the electrode body. The electrode terminal has one end part and another end part arranged along a first direction, the one end part being connected to the electrode body, the other end part projecting to outside the exterior body, and the electrode terminal being composed of a first material. The exterior body has a fixing member that is fixed to the electrode terminal along a second direction intersecting the first direction between the one end part and the other end part of the electrode terminal, the fixing member being composed of a second material that is different from the first material. The relationship (h T)2 (a1/a2) L0=0.222 is satisfied, where h (HV) is the Vickers hardness of the first material, T (mm) is the thickness of the electrode terminal along a direction orthogonal to the first direction and the second direction, a1 is the linear expansion coefficient of the first material, a2 is the linear expansion coefficient of the second material, and L0 (mm) is the length of the electrode terminal fixed to the fixing member along the second direction."
The patent application was internationally filed on Mar. 29, 2024, under International application No.PCT/JP2024/013389.
