CYLINDRICAL ELECTRO-CHEMICAL CELL: CASING TOP CRIMPED TO SEALING MEMBER IN MULTI-STEP METHOD |
| 摘要 |
An improved method for sealing an electrochemical cell comprises applying radial forces to an expanded, upper portion of the cell casing. A resilient sealing member is located in the upper portion so that when the radial forces reduce the diameter of the expanded casing portion the sealing member is compressingly held in place. |
