Wiederaufladbare Nickel-Metallhydrid-Batterie und Verfahren zur Herstellung der negativen Elektrode einer wiederaufladbaren Nickel-Metallhydrid-Batterie

摘要

A nickel-metallic hydride battery has a cylindrically rolled layered 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 negative electrode plate also has a carrier for an electrically conducting mesh which is embedded in the active material at least on one side of the perforated plate near its surface to support its function. The active material is a compound which retains hydrogen, such as nickel hydroxide.
