Metal Oxide Nano-particles and Nano-composite Polymer Electrolytes - Electrodes and Electrolytes in Solar and Galvanic Cells of the Second Generation

Nanocomposite polymer electrolytes and nanophased metal oxide films are tailored and used as electrodes and electrolytes in galvanic and solar cells of second generation. Nano-composites were prepared using PEO γ-irradiated to selected doses and TiO2 nanograins, which treatments largely enhanced the conductivity of these polymer Zn2+-ion conducting electrolytes. Metal oxide nanostructured films based on titanium, cerium and vanadium were investigated as possible working electrodes in solar or galvanic cells of second generation. As the most promissing and complete methods for investigation of morphology and structure of nanosize ordered materials, synchrotron small-angle X-ray scattering (SAXS) methods were applied to study both type of nano-materials.
