✦ Synopsis

The electrolyte composed of a PEO-based polymer complexed with an alkali metal thio/disulfide redox couple is used in an all solid-state electrochemical photovoltaic cell. Total ionic conductivity studies of the electrolytes modified PEO-MT/T, (M = Li, Na, K), where T-stands for 5-mercapto-1-methyltetrazole ion and T, for its dimere, are reported. As expected, the results show that the conductivity values measured at the same temperature increase with the atomic weight of the alkali cation. A maximum in conductivity is found with the system modified PEO-KT/T, prepared at a O/K molar ratio of 8/l.

In this paper, the ionic conductivity of a new polymer solid electrolyte prepared by employing both intermacromolecular complexation and plasticization was studied. The experimental results show that a decrease in the molecular weight of the plasticizer, or an increase in the plasticizer content, le

The conductances of LiC104 and LiCF3SO 3 solutions in a low mol. wt polyether have been measured as a function of salt concentration. The results have been interpreted in terms of ion pair and triplet formation. It is concluded that, at the electrolyte concentrations normally used to form "polymer e
