Abstract

PURPOSE:To obtain a long-life electrode with high porosity prevented from coming- off of active materials by sintering a substrate made by sintering alkali-proof metal fiber chops of a specific fiber diameter, and filled with iron or iron alloy slurry. CONSTITUTION:Fiber chops of alkali-proof metals such as nickel, stainless steel and so on with fiber diameter of 2-100mu are sintered for constructing a sintered substrate with porosity of 85-95%. After being filled with water solution slurry of iron or active materials of iron compound and dried, this sintered substrate is sintered in a reducing atmosphere for obtaining a sintered iron electrode. The length of the above-written fiber chops is preferably chosen within the range of 0.1-30mm.
