Develpoment of Materials and Cell Structure for High Energy Density Flexible Hybrid Electrolyte Lithium Air Batteries

The goal of this research project is to develop flexible composite solid electrolyte materials composed of lithium aluminum titanium phosphate (LATP) or solid inorganic fillers such as TiO2 and highly conductive polymers, to apply these composite solid electrolyte materials as the flexible lithium ion conducting membranes (FCLICMs) needed in hybrid electrolyte lithium air batteries (HELABs), and to actually apply these FCLICMs to HELABs to evaluate their performance, all of which are based on the experience and techniques acquired in the previous research works on development of LATP LICMs and HELABs. In addition, the effects of the compositions of FCLICM (compositions and amounts of inorganic powders, polymers, lithium salts used in the fabrication and solvent selection, etc.) on the characteristics of FCLICM, the effect of gel polymer electrolytes on the performance of HELABs, and the effectiveness of the protection layers deposited on lithium anodes against erosion by water and oxygen from the aqueous electrolyte solution will also be investigated in order to find out the proper materials and cell structure to fabricate flexible HELABs and to finally evaluate the performance and feasibility of HELAB pouch cells.
