MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202617091368 A) filed by Ningde Amperex Technology Limited on July 28, 2026, for Electrode Assembly, Electrochemical Apparatus And Electric Device.
Inventors include Jin, Fudong; and Wu, Hua.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: Provided in the present application are an electrode assembly, an electrochemical apparatus and an electric device. The electrode assembly comprises a first electrode sheet and a second electrode sheet having opposite polarities, wherein a first active material layer and a second active material layer of the first electrode sheet are respectively arranged on a first surface and a second surface of a first current collector that are opposite each other; the first active material layer is provided with a first groove and a second groove penetrating through a bottom wall of the first groove to the first surface; a first surface of a first single-sided bare foil area of the first current collector is exposed in the second groove, and a second surface thereof is covered by the second active material layer, such that the volume of the second active material layer is larger; a first tab is accommodated in the second groove and is welded to the first single-sided bare foil area to form a welded joint; and a first insulating adhesive layer is accommodated in the first groove and covers the welded joint, and the projection of the first insulating adhesive layer in the direction of thickness of the first current collector is located in the first groove, such that the overall thickness of the electrode assembly is smaller, making the energy density of the electrochemical apparatus higher.
