Negative plates for the lead-acid battery with porous carbon grids coated with cooper or copper and
lead have been prepared and tested. In the first stage of the study a method of galvanic coating of the
porous carbon matrix was developed. Analysis of the quality of the metal coatings was based on the
results obtained with a scanning electron microscope. Measurement of the electrical conductivity for a
series of collectors modified with various metal layers was also performed. Additionally, for the
carbon matrix modified with a double metal layer of 20 μm Cu and 20 μm Pb a series of
electrochemical measurements using cyclic voltammetry was performed to investigate its
electrochemical properties and compared with a solid lead electrode. In the study a series of
experimental cells was prepared in which the negative plate collector used: an unmodified carbon
matrix, a carbon matrix modified with lead or copper and a carbon matrix modified with double metal,
copper-lead layer.
