INFLUENCE OF NONEQUILIBRIUM CRYSTALLIZATION ON THE PHYSICOCHEMICAL PROPERTIES BATTERY ALLOY FOR THE NEGATIVE CURRENT COLLECTOR

Annotation. The impetus for research has become the important advantages of lead-acid batteries for the industry: the simplicity of production technology and commercial acceptability. During in this research, emphasis is placed on improving the physical and chemical properties of the lead-acid batteries by improving the conditions for obtaining negative current collectors. As the experimental samples, tapes of industrial production and identical in composition of the belt, obtained by the quenching from the liquid state (QLS) industrial system (wt%) of Pb-Ca 0.1% -Sn 0.3%, which were modified by the optimal (up to 0.03%) by microalloying with barium. All experiments were carried out under conditions of artificial aging, close to the industrial conditions of operation of the lead-acid battery. The performance characteristics of the samples were evaluated by the values of the ultimate strength, elongation, microhardness and corrosion resistance. The obtained results indicate that the strength of the lead-acid battery has been increased several times due to the increase in corrosion resistance by more than 10% due to the proposed QLS method and microalloying of battery alloys of a negative current collector.
