    摘要: An anode structure (15) for a cylindrical primary electrochemical cell. The anode structure in accordance with the invention includes a thin, circular, lithium metal disc (15a) having a central opening (15f) therein, and a small, thin, resilient, metal (e.g., nickel) contact member (15b) secured to the lithium disc (15a). The metal contact member (15b) is of a generally circular configuration and has a flat central portion with a circular opening (15e) therein aligned with the opening in the lithium disc (15a). The contact member has a plurality of tab portions (15d) extending outwardly from, and spaced at regular intervals about, its outer periphery, and a pair of spikes or barbs (15c) depending from opposed ends of each tab portion. The spikes are pressed into the soft lithium disc (15a) at points spaced from the opening therein for permanently securing the contact member to the disc. The contact member further has a plurality of notches spaced at regular intervals about the perimeter of the central opening thereby to define a plurality of resilient, deflective portions intermediate to the notches. The deflective portions lie in a flat, common plane with each of the deflective portions having an exposed edge facing a central axis of the contact member.
