Power and Thermal Technologies for Air and Space. Delivery Order 0001: Single Ionic Conducting Solid-State Electrolyte

摘要

This report focuses on the development of a lithium-ion conducting channel as a solid-state electrolyte for rechargeable lithium batteries through the use of thin films of dilithium phthalocyanine (Li2Pc) which have been solvent cast onto manganese dioxide cathodes. Experimental procedures have been developed which have resulted in the successful deposition of Li2Pc with low ionic resistance. AC impedance measurements and analysis of the equivalent circuit has shown that specific ionic conductivities of 1.9 x 10-4 S/cm at room temperature are achievable. However, it has also been shown that Li2Pc in its current configuration is also an electronic conductor. Development of a thin film insulator based on lithium nitride in conjunction with Li2Pc is now in progress.
