Ionic conductivity and thermal analysis of a high-temperature polymer Journal Articles

abstract

• A high-temperature polymer electrolyte based on lithium-doped pyromellitic dianhydride + Oxybis(aniline)/2,5-diaminobenzenesulfonic acid (PMDA-ODA/DABSA) copolymer has been synthesized and characterized by ac impedance analysis and differential scanning calorimetry. Its dc conductivity was found to reach 10−8 S/cm near 60 °C at ambient relative humidity and was confirmed to be of ionic nature. Besides the increase of the conductivity achieved by moisture uptake, the doping of lithium was found to yield enhancement of the ionic transport in the absence of water molecules as well.
