Enclosed layered stack, eg for batteries, consists of intermediate layers which are sepd from each other, with a wound strip between them.

The invention relates to an enclosed layered stack and to a method for producing said enclosed layered stack from a strip material (1) and several intermediate layers (2). Said method comprises the following steps: a) the strip material (1) is wounded onto a mandrel (3) in order to produce a multilayered winding, the intermediate layers (2) being bent about at most 180 DEG during the winding process and arranged on top of each other, between the winding layers (4); b) the layered stack is clamped into a housing (6) in such a way that the intermediate layers (2) are pressed together without buckling. The invention also relates to the use of this method for producing batteries, accumulators or capacitors. The invention can be used particularly advantageously for producing electrolyte capacitors with cuboidal housings.

Nickel-metal hydride battery

A nickel-metallic hydride battery has a cylindrically rolled laminated material made of a positive electrode, a negative electrode and a separator between them. The negative electrode has an electrolytically active material on both sides of a perforated plate to hold it, serving as a collector. There is an electrolyte and a protective container around the whole lot. The perforation density in the plate is greater in the outer region than in the middle region so that the binding forces between the plate and the material are essentially equal over the whole plate, and the plate's capability to collect electricity is thus increased considerably.
