MUMBAI, India, Nov. 2 -- Intellectual Property India has published a patent application (202617095483 A) filed by Ningde Amperex Technology Limited on August 06, 2026, for Electrode Assembly And Electrochemical Apparatus.
Inventor includes Zhang, Guowen.
The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: The present application relates to the technical field of batteries, and discloses an electrode assembly and an electrochemical apparatus. The electrode assembly comprises a battery cell body, multiple first tab units and a first welding plate, the multiple first tab units being connected to the battery cell body. Some of the first tab units are clustered to form a first tab group, and the remaining first tab units clustered to form a second tab group; along a first direction, the first welding plate has a first surface and a second surface opposite to each other, the first surface facing the battery cell body and making insulated contact with the first tab units, and the second surface facing away from the battery cell body. The first tab group is bent to abut against the second surface, and the second tab group is bent to overlap with and electrically connect to the first tab group. In the present application, the first tab group and the second tab group may be welded, with external conductive sheets, etc., on the same surface of the first welding plate in a third direction to form a staggered configuration, effectively reducing the space occupied in the first direction, reducing the volume of the electrode assembly, and helping to improve the energy density of the electrochemical apparatus.
