Abstract: | Solvent-free, lithium-ion-conducting, composite polymer electrolytes have been prepared by a double dispersion of an anion
trapping compound, i.e., calyx(6)pyrrole, CP and a ceramic filler, i.e., super acid zirconia, S-ZrO2 in a poly(ethylene oxide)-lithium bis(oxalate) borate, PEO–LiBOB matrix. The characterization, based on differential thermal
analysis and electrochemical analysis, showed that while the addition of the S-ZrO2 has scarce influence on the transport properties of the composite electrolyte, the unique combination of the anion-trapping
compound, CP, with the large anion lithium salt, LiBOB, greatly enhances the value of the lithium transference number without
depressing the overall ionic conductivity. These unique properties make polymer electrolytes, such as PEO20LiBOB(CP)0.125, of practical interest, as in fact confirmed by tests carried out on lithium battery prototypes. |
