Abstract
A low volume collector assembly and an electrochemical cell employing a collector assembly are provided. The electrochemical cell includes an electrically conductive can having inner and outer electrodes disposed therein. The cell also includes a collector assembly assembled to an open end of the can to provide closure to the open end of the can. The collector assembly includes a seal and a cover assembled to the seal to provide a sealed closure to the open end of the can. The cover includes an integrally formed current collector portion that contacts one end of the inner electrode. The cover serves as a current collector and also serves as a contact terminal of the cell.
