Aerospace Power Scholarly Research Program. Delivery Order 0011: Modeling Lithium-Ion Conducting Channel

Abstract

This report focuses on the development of a lithium-ion conducting channel as a solid-state electrolyte for rechargeable lithium batteries. Dilithium phthalocyanine (Li2Pc) has been used in this development since it can undergo molecular self-assembly to form the ionic ally conducting channel. The essential features of the channel are that it is designed such that the anion matrix of the unsaturated macrocycle forms the channel through which the lithium ions moves, thus making it a single-ion conductor for lithium ions; the ionic transport of lithium depends on the electric field gradient created by the electrodes, thereby minimizing temperature dependence for ionic transport. Part II of this study shows that Li2Pc preferentially aligns with the galleries of the iron sulfide cathode thereby facilitating lithium-ion transfer between the electrolyte and the cathode.
