Abstract
An electrode composed of a mixture of electrochemically active particles and metal powder compressed onto a metal foil strip can be inductively sintered without localized overheating by passing the coated strip through a hairpin-shaped inductor provided with widened portions facing the edge regions of the strip, so as to locally increase the cross section of the hairpin in the portions of the hairpin that are opposed to the edge regions of the electrode strip. This arrangement counteracts the tendency of the edge regions to overheat and thermally damage the active material.
