Abstract

A method for manufacturing an iron-containing sintered electrode for alkaline accumulators as well as the product obtained by such method, in which iron powder and at least one reducible iron compound are intimately mixed with each other; the powder mixture is sintered into a stable body and the reducible iron compound is reduced to highly active iron.
