Abstract—In the work, the regularities of electrodeposition of composite materials based on PbO₂ containing
the valve metal particles are considered. The content of dispersed phase in the composite depends on the elec-
trolyte composition and conditions of deposition. The incorporation of titanium particles into PbO₂ consider-
ably changes the deposit morphology. It is found that the service life of electrodes containing dispersed Ti phase
increases by 4 times as compared with the conventional anodes made of pure PbO₂.

Key words: composite materials, electrolysis, suspension electrolyte, dispersed phase, lead dioxide
