There is no doubt that, in the last decades, the need for a portable power source has increased due to the miniaturization of electronic appliances. Also, the operation of some diminutive electric devices has been possible thanks to the development of the technology for very little power sources which require, in many cases, low power and, because of this, the science of the semiconductor materials has made a remarkable progress. The demand for batteries with high energy densities has inevitably led to the research and development of systems involving thermodynamically more stable than aqueous electrolytes. The opportunities for extreme miniaturization and for very simple production techniques are of obvious importance in applications and reliability, which are key factors.Finally, from the microscopic results like FTIR, we have learned that different modifier oxides involve different local order, essentially, in the kind of tellurium polyhedron mainly present in the glassy matrix. We are interested in this kind of knowledge because it will be useful to understand how to control the structure in the middle-range order, which isrelevant in the electrical conduction process and as a consequence, in the technological applications of these materials as solid electrolytes.
