Description: The aim of the HiPoCat project (Highly Porous Cathodes for Lithium-Air Batteries) is to evaluate metal-organic frameworks (MOFs) and zeolitic imidazolate frameworks (ZIFs) for use as new precursors for cathode materials for Li-air batteries. Through pyrolysis of the highly microporous MOFs and ZIFs, cathode materials with high electronic conductivities, reactivity, and corrosion resistance will be synthesized. Furthermore, thermal analysis and kinetic modelling approaches will be used to determine the pyrolysis parameters leading to optimal porosities. The cathode materials that are developed in this work will be combined with suitable electrolytes and electrolyte additives to assemble Li-air batteries which display specific capacities, coulombic efficiencies, and rate-capabilities which are significantly higher than those of the conventionally used carbon-based cathodes. Additionally, the porous gas-diffusion cathodes will be produced using a lower number of synthesis steps and environmentally-friendly aqueous solvents, which will be a technological first in Austria.
