Nonaqueous electrolyte battery and production method thereof |
摘要 |
A nonaqueous electrolyte battery includes: an electrode body having at least a positive electrode and a negative electrode; a cylindrical container with its bottom closed, in which the electrode body and a nonaqueous electrolytic solution are contained; and a lid body for closing an opening portion of the container. The lid body has a lid portion which constitutes a peripheral edge portion of the lid body, a projecting portion which constitutes a central portion of the lid body, and a stepped portion which has a vent hole and is positioned between the lid portion and the projecting portion. A metal plate having a through-hole is disposed between the lid body and the electrode body. With this configuration, it is possible to prevent the movement of the battery by a motive force generated when a decomposition gas generated in an abnormal state is discharged to the outside of the battery, and hence to improve the reliability of the battery. |
