MUMBAI, India, Aug. 17 -- Intellectual Property India has published a patent application (202617079404 A) filed by Ningde Amperex Technology Limited on June 27, 2026, for Electrochemical Apparatus And Electric Device.
Inventors include Chen, Tengteng; Li, Xun; Chen, Wen; and Lao, Shaojiang.
The application for the patent was published on August 14, 2026, under issue no. 33/2026.
Abstract: The present application discloses an electrochemical apparatus and an electric device. The electrochemical apparatus comprises an electrode assembly and a housing; the housing has a first side wall and a second side wall which are oppositely arranged in a first direction; the first direction is the thickness direction of the electrode assembly; the electrode assembly is arranged between the first side wall and the second side wall; the first side wall has a first outer surface and a first inner surface; the first outer surface is distant from the electrode assembly relative to the first inner surface; the first outer surface is provided with a first protrusion; the first inner surface is provided with a first recess at a position opposite to the first protrusion; the orthographic projection of the first protrusion on a first plane is located in a first angular region of the orthographic projection of the first side wall on the first plane; and the first plane is perpendicular to the first direction. According to the electrochemical apparatus of the present application, by providing the protrusion in the angular region of the first side wall, the stress borne by corners of the housing can be reduced when the electrode assembly expands, thereby reducing the risk of damage to the corners, and improving the reliability of the electrochemical apparatus during use.
