Coiled electrode assembly cell construction with telescopic terminal tab

摘要

The invention relates to a cell employing a coiled electrode assembly having the edge of at least one electrode strip protruding above the coiled electrode assembly and wherein said electrode edge is electronically connected to a tab having a telescopic center portion that can flex below and then above the plane of the tab so that any bulge in the cell's housing will flex the tab without disturbing the electronic contact between the cell's housing and the edge of the electrode strip protruding above the coiled electrode assembly.
