Novel, Solvent-Free, Single Ion-Conducting Polymer Electrolytes

Abstract

The work carried out within this project has lead to the development of new types of dual composite PEO-based electrolytes having outstanding properties. This also, and particularly, applies to the new member of the family discussed in this report, i.e. the electrolyte formed by the combination of a calyx(6)pyrrole, CP anion-trapping compound with a large anion lithium salt, such as lithium bis(oxalate) borate, LiBOB. The results here described show that this combination gives rise to PEO-based polymer electrolytes having excellent transport properties. Polymer electrolyte membranes of the PEO20LiBOB(CP)0.125 composition have in the 80 C temperature range a lithium transference number of about 0.5 (versus the 0.3 value of conventional PEO systems) and an ionic conductivity of the order of 0.001 Scm-1.
