Synthesis of new materials with elevated electronic and/or ionic conductivity to be used in electrochemical devices for energy generation (fuel cells) and energy storage (batteries and supercapacitors). In preparation of materials soft chemistry techniques (e.g., coprecipitation, Pechini method), and thermal treatments in different atmospheres are used.

Moreover, synthesis of new metal hydrides, by hydrogenation under high pressure of intermetallic alloys of light elements will be also prepared (hydrogen storage). Finally, nanosized and nanostructurated materials for the different applications will be prepared by self-combustion, templating methods, electrochemical etching, functional coatings and ion implantation techniques.

Compositional, structural and textural characterization of the new materials obtained. The structural characterization, which will be carried out by X-ray and neutrons powder diffraction, NMR, Raman and IR spectroscopy, is aimed to establish relationships between structure and transport properties. In particular, the localization of certain light elements, such as O, H or Li ions, present in materials for fuel-cells, hydrides or fast-Li conductors can explain many of their properties.

Micro- and nanostructural characterization, carried out by HRTEM, EELS, XEDS, Raman and optical microspectroscopies, will allow a better understanding of the distribution of the different components (active material and additives) that comprise the electrodes or the electrolytes in the devices. From these data, the distribution of the components and their electrical properties will be correlated.

The electrical and electrochemical properties of the synthesized materials will be studied. The electrical measurements carried out from d.c. up to the microwaves region permit to know the electrical conduction mechanism in the active materials, as well as in the electrodes and electrolytes comprising the devices.

The analysis of the relationships between structure and transport properties will allow optimizing the ionic/electronic conductivity. Capacity and capacitance of the electrodes will be measured and discussed in relation to structure and texture. Extended cycling studies will allow appropriate assessment of the cycle life of electrochemical storage materials and devices.

Design and development of prototypes of electrochemical devices for energy generation (fuel cells) and for energy storage of electric energy (supercapacitors and batteries). From the materials showing the best electric performances new propotypes of fuel cells, supercapacitors and batteries will be developed. This task will be done in cooperation with private companies and technological centres.
