MUMBAI, India, Sept. 22 -- Intellectual Property India has published a patent application (202617077923 A) filed by Ningde Amperex Technology Limited on June 24, 2026, for Sealing Member, Battery Module And Electrical Device.
Inventor includes Zhang, Guowen.
The application for the patent was published on September 18, 2026, under issue no. 38/2026.
Abstract: A sealing member, a battery module (100) and an electrical device (200). The battery module (100) comprises a housing (10), a battery cell (20), a first sealing member (30), and a second sealing member (40). The housing (10) is provided with a first through hole (10a), a second through hole (10b) and an accommodation space (10c), the first through hole (10a) being communicated with the accommodation space (10c), and the second through hole (10b) being communicated with the accommodation space (10c). The battery cell (20) is arranged in the accommodation space (10c). The first sealing member (30) is connected to the housing (10) and seals the first through hole (10a). The second sealing member (40) is connected to the housing (10) and seals the second through hole (10b). The first sealing member (30) is configured to melt and/or lose adhesiveness when the internal temperature of the battery module (100) reaches a first temperature, so as to form a first pressure relief channel, and the second sealing member (40) is configured to melt and/or lose adhesiveness when the internal temperature of the battery module (100) reaches a second temperature, so as to form a second pressure relief channel, the second temperature being higher than the first temperature. The second temperature of the second sealing member (40) being higher than the first temperature of the first sealing member (30) facilitates pressure relief and reduces the risk of short circuit between the battery cell (20) and the housing (10), thus improving the safety and pressure relief reliability of the battery module (100).
