Methode zur Herstellung einer gasdicht verschlossenen elektrochemischen Zelle.

摘要

An electrochemical cell [1] comprising a negative electrode [6] whose electrochemically active material includes an intermetallic compound which can form a hydride with hydrogen, the cell comprising an electrolyte of a solution of at least one alkali hydroxide in water, the negative electrode being provided with a discharge buffer by introducing a quantity of an alkali metal [11], alkaline earth metal or aluminium into the cell before the cell is sealed, the quantity corresponding to the desired quantity of hydrogen in the negative electrode in the uncharged condition of the cell.
