Abstract

1386497 Making electrodes; jointing; welding by pressure E I DU PONT DE NEMOURS & CO 31 July 1972 35681/72 Headings B3A B3V and B3R [Also in Divisions E1 and H1] A composite galvanic cell electrode is made by bonding lithium to a conductive metal selected from stainless steel, aluminium and zinc. The conductive metal is etched in a mixture of aqueous hydrochloric and nitric acids and then washed and dried to remove the acid and any deposits formed in the etching step. The etched conductive metal is pressed into contact with a freshly prepared lithium surface to form a metallurgical cold bond preferably in an atmosphere of argon. The fresh lithium surface may be prepared by abrasion, cutting or scraping. Adhesion of the lithium to the conductive metal may be effected with a pressure of from 0À1-2À0 kg./cm.<SP>2</SP> for a period of from 0À1-5À0 secs. An example of a bipolar electrode is described in which a copper sulphide cathode is placed on one side of a stainless steel plate and a lithium anode is placed on the other side of the plate.
