Scientific activities of the Solid State Ionics Division:

The main area of scientific activity of the division is physics of superionic conductors, i.e. solid materials exhibiting high ionic conductivity approaching 0,1 S/cm. Electrical properties of superionic conductors and their correlations with composition, crystal structure and other physical properties are investigated. Prospects of applications of these materials in electrochemical cells for energy conversion and storage or in chemical sensors is studied. The scope of th research includes also preparation technologies of new superionic conductors under study.

The division consists of two scientific groups:

• Crystalline Superionic Conductors Group (W. Bogusz, F. Krok, M. Dynarowska, J.R.Dygas, P.Kurek, M. Malys, M.Marzantowicz, W.Wróbel and PhD students: A.Borowska-Centkowska, M. Krynski, M.Leszczynska, M.Struzik) has investigated such crystalline materials as cationic lithium and sodium and anionic, oxygen ion conductors based on Bi2O3 - mainly BIMEVOXes. Another topic of interest is polymer electrolytes based on PEO. The studies are focused on the relation between ionic transport and crystal and defect structure of those materials.
  
  
• Amorphous Superionic Conductors Group (J.E.Garbarczyk, M. Wasiucionek, J. L. Nowiński, B. Wnętrzewski and P. Jóźwiak and PhD students: M.Aksienionek, M.Czak, P.Grabowski, A.Kalbarczyk, D.Nowakowski, T.K.Pietrzak, W.Slubowska) investigates highly conductive glassy, composite, glassy-nanocrystalline and gel materials. Among investigated conductors there are silver superionic glasses of the AgI-Ag₂O-V₂O₅ system, proton conducting glasses of
  H-UO₂-IO₆-H₂O system, mixed ionic-electronic conducting glasses of the AgI-Ag₂O-V₂O₅-P₂O₅ system, lithium conductive gels based on SiO₂.

Both groups investigate also intercalated compounds with mixed electronic-ionic conductivity.
