Abstract : During this period the activities have been focused on the preparation and the characterization of the first set of polymeric electrolyte samples to be sent to the U.S. ARL, Ft. Monmouth, NJ. This set is constituted by an adequate quantity of samples with the following molar composition: (1) PAN 16/ PC 23/ EC 56.5/ LiClO4 4.5; (2) PAN 16/ PC 23/ EC 56.5/ LiAsF6 4.5; (3) PAN 16/ PC 23/ EC 56.5/ Li-Imide 4.5. These samples have been prepared following the preparative route described later in the text and characterized by determining ionic conductivities, cationic transference numbers and the electrochemical stability windows. All the preparation procedures of the gel electrolytes and the related electrochemical measurements were carried out in an Argon filled glove box whose atmosphere had a moisture content constantly lower than 5 ppm. jg p1
