Abstrakt: Abstract: In this paper, the influence of carbon components in the composition of graphite paste on the electrical resistivity of a screen-printed carbon electrode is investigated. Graphite pastes with different contents of thermally expanded graphite (4.5–7.0 wt %), fine-grained graphite (0–6 wt %) and carbon black (0–12 wt %) are investigated. The creation of a polydisperse conducting system requires the application of carbon materials with different physical properties and particle sizes. This will lead to improvement in the screen-printing quality and reduce the resistivity of screen-printed carbon electrodes.
