  • Method of manufacturing highly porous electrode bodies for electrical accumulators and electrode bodies thus obtained
    Patent number: 4206271
    Abstract: A method is disclosed for the manufacture of a highly porous nickel electrode body for electrical accumulators. The new electrode body is also disclosed. By using 5-7% by volume of a nickel powder in admixture with 93-95% by volume of a pore-forming agent selected from the group consisting of ammonium bicarbonate and ammonium carbonate when pressing and sintering the electrode body a very high porosity is obtained, such as 90-95%, in spite of which the mechanical strength of the body is so high as to resist the strains of an accumulator cell. Especially preferable to impart outstanding strength to the electrode body, is a pressure of at least 100 MPa in the pressing operation.
