发明名称 Thermally formed tab slots in a separator for a spirally-wound electrochemical cell
摘要 An electrochemical cell and electrode assembly are disclosed in which a separator having at least one thermally formed tab slot disposed therein is employed in conjunction with an alkali metal anode and a cathode assembly that are wound together in a unidirectional winding having substantially straight sides such that the winding will fit into a prismatic cell. The separator inhibits tearing or splitting of the material from which it is formed in the region of the tab slot. A tab connected to a current collector projects through the tab slot. The tab slots are formed by folding a separator material around a template, aligning the template with a slot guide, and applying heat to the separator material in the region of the slot(s).
