The effect of waste material electrode on the properties of positive electrodes in lead-acid batteries

JANKOWSKA E., MAJCHRZYCKI W., MARTYŁA A., MAJCHRZYCKI Ł. Please Cite as: CHEMIK 2016, 70, 11–12, 691–702 The study allowed to observe changes in morphology and phase composition of plates depending on the amount of introduced waste material. The phase composition of positive electrodes measured after the formation process showed no significant differences between groups with different content of waste material. The positive plates with waste electrode material addition revealed presence of 4PbO·PbSO4 which was absent in the...

Thermoplastic polyurethane-based nanocomposites reinforced with carbon fillers

STAFIN K., LESZCZYŃSKA A., PIELICHOWSKI K. Please Cite as: CHEMIK 2016, 70, 11–12, 685–690 Thermoplastic polyurethane (TPU) behaves both as a crosslinking rubber and thermoplast at ambient temperature during use and at elevated processing temperature, respectively. In this paper, thermoplastic polyurethane reinforced with carbon nanofillers (e.g. carbon nanotubes, graphene and expanded graphite) was presented. Carbon nanofillers improve mechanical strength, thermal stability and are effective modifiers for manufacturing electrically conductive nanocomposites. Improved or new properties of TPU nanocomposites...
