Abstract

In Lithium secondary cells, alkali secondary cells and bromine-zinc secondary batteries capable of retarding the growth of a dendrite, which would occur at the time of charging thereof and result in performance degradation, and having high energy densities and long cycle lives, a method for forming a material of a negative electrode of such a secondary cell or battery and a method for handling the material of the negative electrode are provided. The secondary cell or battery is provided with positive and negative electrodes separated from each other by a separator in an electrolyte contained in a case. The negative electrode is made of metallic powder alloyed with at least an amphoteric metal which reacts with both of an acid and an alkali.
