ELEKTRISCHER AKKUMULATOR IN FORM EINER KNOPFZELLE

摘要

A button cell contains one or more sets of electrodes enclosing an opposite polarity electrode and mechanically and electrically connected at peripheral regions. A button cell has a housing containing one or more electrode sets of an electrode of one polarity positioned between two opposite polarity electrodes which are mechanically and electrically connected at peripheral regions to form a mechanically stable electrode packet. An Independent claim is also included for production of the above button cell. Preferred Features: The positive electrodes contain nickel hydroxide active material and the negative electrodes contain a hydrogen storage alloy or cadmium active material. Alternatively, the positive electrodes contain a lithium ion-containing chalcogenide active material and the negative electrodes contain a lithium acceptor compound active material.
