ABSTRACT:
A zinc negative electrode comprising a zinc active material, Ba(OH).sub.2 or Sr(OH).sub.2 and a conductive matrix including a metallic oxide which is more electropositive than zinc. The zinc negative electrode is incorporated into a zinc secondary battery having an electrolyte whose electrolyte constituent is a low percentage of the electrolyte. The zinc negative electrode is split into electrode assemblies separated by a porous hydrophobic element.
