Abstract

A mixture of a water-soluble silver salt (silver nitrate) and a ground carbon and/or powdered graphite is made, with inclusion of a pore-former if necessary. A little water is added and the mixture mixed with an aqs. emulsion of a binder PTFE. The mass, before or after drying, is worked under pressure to a foil which can be activated wet or dry with an aqs. alkali hydroxide soln.
