Journal ArticleDOI
Electrochemical behavior of metal hydrides
Janis Kleperis,Grażyna Wójcik,Andrzej Czerwiński,J. M. Skowroński,Maciej Kopczyk,Maria Bełtowska-Brzezinska +5 more
TL;DR: In this article, the effect of the chemical nature and stoichiometry of specific alloy families (AB5, A2B, AB/AB2 and AB2) on the hydride stability, hydrogen storage capacity and kinetics of hydrogen sorption-desorption in the solid phase/gas and solid phase-electrolyte solution systems is discussed.
Journal ArticleDOI
Electrochemical behavior of lead in sulfuric acid solutions
Andrzej Czerwiński,Malgorzata Żelazowska,M. Grdeń,K. Kuc,J.D. Milewski,A. Nowacki,Grażyna Wójcik,Maciej Kopczyk +7 more
TL;DR: In this article, the electrochemical behavior of the lead electrode has been studied by cyclic voltammetry (CV) in sulfuric acid solutions, with concentrations ranging from 0.05 to 5 M.
Journal ArticleDOI
Hybrid lead-acid battery with reticulated vitreous carbon as a carrier- and current-collector of negative plate
Andrzej Czerwiński,S. Obrębowski,J. Kotowski,Zbigniew Rogulski,J. M. Skowroński,M. Bajsert,M. Przystałowski,M. Buczkowska-Biniecka,E. Jankowska,M. Baraniak,J. Rotnicki,Maciej Kopczyk +11 more
TL;DR: In this paper, a negative plate carrier-and current-collector material for lead-acid batteries was investigated and the promising results showed that application of RVC as carrier and current collector in negative plate will significantly increase the specific capacity of leadacid battery.
Journal ArticleDOI
Electrochemical behavior of nickel deposited on reticulated vitreous carbon
Andrzej Czerwiński,M. Dmochowska,M. Grdeń,Maciej Kopczyk,Grażyna Wójcik,G. Młynarek,J. Kołata,J. M. Skowroński +7 more
TL;DR: In this paper, the electrochemical performance of reticulated vitreous carbon (RVC) has been investigated in solutions of KOH and showed that the RVC covered with nickel is a good carrier for Ni(OH) 2 /NiOOH.
Journal ArticleDOI
Electrochemical behavior of lead alloys in sulfuric and phosphoric acid solutions
I. Paleska,R. Pruszkowska-Drachal,J. Kotowski,A. Dziudzi,J.D. Milewski,Maciej Kopczyk,Andrzej Czerwiński +6 more
TL;DR: In this article, the electrochemical behavior of lead, lead-antimony, and lead-calcium-aluminium-tin alloys has been studied in solutions containing various concentrations of sulfuric and phosphoric acids.
