Modified Li-Ion Conducting Ceramic Membrane for Improved Performance in Hybrid Li-Air Battery

Li-air battery (LAB) with non-aqueous electrolytes currently has insurmountable technical challenges in both electrolytes and solid lithium oxide products [1-2]. A hybrid Li-air (HyLAB) system has been reported as an alternative approach [3-8]. Such systems use non-aqueous electrolyte in the anode and aqueous electrolyte in the cathode. A Li-ion conducting ceramic membrane (water impermeable) is used to separate the anode and cathode chambers. While such hybrid system can avoid many problems in the aprotic system, unfortunately, the ceramic membrane is not stable in acidic or alkaline electrolytes.

In this presentation, we report our recent work to modify the ceramic membranes. We will demonstrate that by modifying the Li-ion conducting ceramics it is possible to improve its resistance to corrosion and therefore increase the performance of the HyLABs. We will discuss the technical details of the work in this presentation.
