ABSTRACT:
A flat zinc anode useful in cells and batteries, e.g., Leclanche batteries, is produced by coating an electrically conductive substrate with a slurry of zinc dust and an aqueous polymer latex in which the polymer particles have been swollen by an alcohol. The amount of the polymer is about 0.5 to 5 weight per cent based on the amount of zinc. The amount of polymeric binder is not sufficient to form a continuous film but rather forms an adhesive mass which holds the zinc dust particles in place. Many polymers are suitable for use as binders, and it is presently preferred to employ, e.g., soft vinyl polymers, acrylates, or elastomers which do not react with zinc to impair battery performance or stability of the mix.
