Abstract

1419785 Cell electrode manufacture VARTA BATTERIE AG 1 Dec 1972 [10 Dec 1971] 55585/72 Heading H1B In the manufacture of an electrode for an alkaline cell, dry silver (II) oxide powder is mixed with dry P.T.F.E. powder and the mixture is subsequently formed into an electrode solely by compression, with or without a supporting material, by subjecting the mixture to a pressure of from 0À5 to 3À0 t./sq. cm. Preferably the P.T.F.E. has a particle size of from 10-50 Á and is present in an amount of 1-10% by weight of the silver oxide powder. The dry silver (II) oxide powder may also include some particulate silver. Initially the P.T.F.E. powder is mixed with 10% by weight of the silver powder, the remainder of which is added subsequently. The pressure employed on the mixture to form the electrodes is preferably 1 t./sq. cm. A silver, copper or silverplated copper support for the electrode in the form of a net, fabric or nail-perforated or sintered foil may be provided.
