Abstract

An electrically conductive first component (2) on an electrochemical cell is formed at a surface with protruding tongues or flanges (4) extending through a transition zone into an adjacent parallel second component (6) of the cell such as a layer of active material so as to present surfaces (5, 7) to the material of the second component in the transition zone which face both forwards and away from the surface of the first component so as to improve the physical, electrical and thermal interaction of the components and distribute that interaction through the transition zone.
