| Zusammenfassung: | A battery cathode sealing device comprises a sealing cover board arranged at an open end of a battery metal shell; a cathode component arranged on the sealing cover board, extending upwards from the battery metal shell outward the cover board; a sealing piece between the cathode component and the sealing cover board to make the cathode component and the sealing cover board form a sealing connection The invention effectively solves the problem of battery cathode leakage. The leakage points of the battery are completely sealed by the multiple sealing structure so as to effectively prevent the battery cathode leakage and avoid the battery and device damage due to the leakage liquid. |
