Project Details


The goal of this research project are to synthesize high conductivity lithium ion conducting membranes (LICM) for high efficiency lithium air batteries (LAB) and develop corresponding manufacturing processes and techniques. To fulfill the goal of the integrated research project to develop high efficiency LAB with mixed aprotic/aqueous electrolyte configuration, ceramic membranes with high lithium conductivity (10-3 Scm-1), high relative density, and low porosity must be developed along with related materials and processing techniques to effectively separate aprotic and aqueous electrolytes and to guarantee high performance of LAB. Although there are four types of inorganic lithium ion conductors (LIC) (Perovskite, NASICON, LISICON and Garnet), only the former two types will be evaluated due to the lithium ion conductivity requirement (10- Scm- ) of the ceramic membranes that should be used for LAB. By variation of the material composition and the processing condition of the ceramic membranes, attempts will be made to fulfill the requirements (high lithium conductivity, high relative density, and low porosity) for ceramic membranes used for mixed aprotic/aqueous electrolyte configuration LAB. By reducing the thickness of the ceramic membranes, the overall resistance of the LAB can be reduced and this can lead to the improved performance of LAB. In developing high relative density LICMs, synthesis techniques for high relative density LICs will also be developed. These techniques can be used to fabricate their corresponding sputtering targets. By depositing the LIC on the polymer membranes developed in other research project in the integrated research project, composite ceramic/polymer electrolyte membranes with reduced ceramic membrane thickness and reduced resistance can be fabricated and used to enhance the performance of LAB.
