A battery cell including a cylindrical container having a cap assembly positioned in the open end thereof. The cap assembly includes a terminal extending into the container, a rigid plate, a thermal disconnect assembly and a contact cap. A seal fits about the cap assembly to electrically isolate the cap from the container and provide a sealing function and vent for the battery. A sleeve is associated with the seal to tightly seal the terminal. The terminal is associated with a spiral wrapped cell by means of a tab welded thereto. The cell is assembled in a flat layered arrangement and then wrapped about the terminal prior to placement in the container.
