Studies on: influence of
the electrode surface structure on the double layer, and on the processes of
adsorption and electrocatalysis; electrocrystallization of metals; influence of the crystallographic structure on the form and
spreading of monoatomic layers; mechanism of atoms’
incorporation in the crystal lattice.
A new trend is the
research on hydrogen storage and metal-hydrides.

Enzyme electrodes for
glucose and lactate monitoring for use in the medicine and biotechnology are
studied. A new type of enzyme/gas-diffusion electrode is developed and used in
biosensors for direct detection of some toxic compounds in waters, soils and in
the air. Air gas-diffusion electrodes with high effective non-platinum catalysts
are introduced. Primary and mechanically rechargeable zinc-air cells are in production. An original idea for environmentally friendly cells is realized on Mg-air cells with seawater electrolyte.

Fundamental research is carried out in the field of impedance analysis, transient technique and spectral analysis, electrochemical noise analysis; methods for non-stationary analysis, evaluation and quality control of electrochemical power sources. A mathematical method is proposed for impedance analysis of non-stationary systems. An original approach for impedance model recognition, called Differential Impedance Analysis, is developed. A new trend in this department is the development and implementation of e-science instruments for efficient virtual research and collaboration in the field of Electrochemical Impedance Spectroscopy.

The activities concerning Li-batteries follow the
advanced ideas for synthesis of high efficient, low
cost intercalation compounds and
nanostructured composite materials for
primary and Li-ion batteries.
Investigation of
intercalation compounds of metal oxides suitable for high energy density
positive electrodes of 3 V secondary lithium batteries is in progress. Synthesis
and study of the structural, physicochemical and electrochemical characteristics
of LiMn2O4 for 4 V lithium systems is performed. Materials
such as lithium/carbon intercalation compounds are investigated as a new lithium
electrode alternative.

Isotropic and anisotropic metal and intermetal nanoparticles, nanowires, nanorods and nanochains containing hydrogen, boron or nitrogen, with tailored
quantum-influenced properties, are synthesized by the boronhydride method. They find application as catalysts and
electrocatalysts, as well as in electrochemical energy sources.
