Considerable advances have been made in recent years in searches for and practical utilization of macromolecular surfactants which can be adsorbed on metals and their oxides both in acid and in alkaline media and which alter the course of electrochemical processes. Polyethylene oxides (PEO) and their derivatives are of definite interest among macromolecular surfactants. The structure of cathodic metal deposits is improved and formation of dendritic deposits is hindered in presence of PEO; this is important for prolonged and stable operation of galvanic cells. The mechanism of interaction of PEO and its derivatives with electrode surfaces by controlled changes in active groups of the molecules was determined. The influence of the surfactants on the cathode and anode processes on zinc and cadmium was investigated. It was concluded that the characteristics of batteries with zinc and cadmium electrodes can be improved considerable and their life lengthened by the use of polymers based on PEO.
