Products, Investigations and Applications
Nanoparticles as
precursors for alkaline and MH batteries
The object of interest is
the original technological processes and reactors for production of metal
clusters and nanoparticles. Their chemical composition could contain one, two or
more elements selected from a list of 40 elements (Fe, Co, Ni, Cu, Pd, Li, Mg,
Ca, Sr, Al, Zr, W, Pb, Sb, V, Mo , Sn, Si, Cr, La, Ce, Sm, Pr, Y, Nd,
Th, etc. boron, nitrogen and hydrogen). Recently, these nanoparticles have been
used as precursors for MH electrodes.
Investigations of
nanoscale materials
Comparative studies of nanoscaled materials by means of electrochemical, common
physicochemical methods, X-ray photon spectroscopic and impedance spectroscopic
methods are the subject of many investigations. They include estimation of nanoscaled size, structure, compositions, quantum size
effects and self-organisation processes, as well as nanoparticles' properties, which lead to their most appropriate application.
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.
