There is provided an elastic laminate of a base layer with one or more attached elastic elements forming an elastic region. The elastic region width varies from a terminal end of the elastic tab to a proximal end of the elastic tab such that a width adjacent the terminal end is 20 to 80 percent narrower than a width adjacent the proximal end. The elastic region is defined by a plurality of segments, having differing average widths in the length direction of the elastic tab elastic region. The one or more elastic elements vary in one or more properties such that a plurality of the segments having different widths have substantially the same degree of elongation at a given elongation of the shaped elastic tab laminate.

Shaped elastic tab laminates

Described are methods of making electrodes for electrochemical systems, especially cathodes for lithium polymer batteries, and products prepared from the methods; the methods involve the use of a co-rotating, fully intermeshing twin screw extruder, the extrusion of essentially solvent-free systems, or both.
