Abstract
A process for the manufacture of an electrode for lead-acid storage battery wherein a current-conducting backing is subjected to electrochemical treatment, to produce an active material. Said active material is formed from the outer layer of the current-conducting backing. The active material is subjected to compression by applying a pressure to the surface thereof.
Claims13
A process for the manufacture of an electrode for a lead-acid storage battery comprising passing electric current through a current-conductive backing of lead immersed in electrolyte and connected to a positive terminal of a power supply, and oxidizing the lead to form a layer of active material on the surface of said current-conductive backing as a result of electrochemical reaction, said active material consisting essentially of PbO.sub.2,
- wherein said process comprises the following steps:
- arranging a current-conductive backing of lead between layers of corrosion-resistant porous material, which during active material formation on the current-conductive backing create pressure on a surface of the formed layer of active material ranging from 0.005 to 6.5 MPa;
- and
- carrying out electrochemical treatment until the active material thickness reaches 0.3 mm to 5 mm.
