Abstract
Poly(ethylene oxide) (PEO) based-polymeric solid electrolytes are of growing interest for their applications in electrochemical devices. Their major limitations are structural and electrochemical stability, and low cationic transport number. A possible response to these problems is given by composite or nanostructured materials. We present sol-gel synthesis, thermal and electrical characterization of new electrolytes made of a composite glass-polymer matrix doped with LiClO4 and LiBF4. Emphasis to the critical aspects of preparation is given. We obtain a conductivity at room temperature better than 10−5 ohm−1 cm−1, which is high enough to envisage technological applications.
