Ionic conductivity stoichiometric salts

The parameter c Eqn (2.1), is capable of variation by many orders of magnitude in ionic solids. In good solid electrolytes such as Na "-alumina and RbAg4l5, all of the Na /Ag ions are potentially mobile and hence c is optimised. At the other extreme, in pure, stoichiometric salts such as NaCl, ionic conduction depends on the presence of crystal defects, whether... 

A series of nonstoichiometric protic mixtures were made from various molar ratios of 2,5-diphenyl-l,3,4-oxadiazole (DOD) with HTFSI and with a polymerizable version of the base. The stoichiometric salt had a melting point of 80 °C and a decomposition temperature of 200 °C, and because of features in tte DSC traces that corresponded to the acid and the base, it was conclnded that there was incomplete proton transfer. The highest ionic condnctivity was for the salt with DOD/HTFSI of 8 2. When a polymerizable version of the base was used, the resulting polymeric systems had veiy low ionic conductivity.
