The invention is directed to a radical improvement of the specific electrochemical and corrosive characteristics of a lead-acid battery without a drastic change in the process of battery producing. The lead-carbon metal composite material contains from 0.1 to 10% by weight of carbon, lead is the remainder, while the structure of the material contains carbon allotropic modifications from graphene to graphite. The method for material synthesizing is characterized in that lead or its alloys are melted in a melt of alkaline and/or alkaline earth metal halides containing from 1 to 20 wt. % of metal carbides or non-metals with a particle size of 100 nm to 200 μm, or solid organic substances, for 1-5 hours at a temperature of 700-900° C.
