Structural and Electrochemical Characteristics of Porous Lead Electrodes with Additive Nanostructured Carbon

The effect of carbon materials of two types was studied: multi-walled carbon nanotubes (“Art-nano” of the NSU “S” brand (TU BU 690654933.001.-2011)) and multilayer graphene (“Art-nano GT” (TU BU 691460594.004–2017), and modifications by treatment with ozone and dimethylformamide (manufacturer LLC Advanced Research and Technology, Belarus) on the structural characteristics, capacity and utilization of the active mass of the negative electrode of a lead-acid battery. It was found that the highest utilization of the active mass are observed using carbon materials “Art nano” NSU “C” and “Art nano-GT”, treated with dimethylformamide. The introduction of carbon additives has an effect on the porous structure of the electrodes: the proportion of small pores, the total porosity and the specific surface of the electrodes increase.
