This work aims to study the gas-diffusion electrode behavior in various non-aqueous electrolytes, potential candidates for use in lithium-air battery, and also its work in a semi cell against lithium metal electrode. Gas-diffusion electrode was prepared with two catalysts–pyrolyzed CoTMPP and Active Carbon Co/Ni tested in a standard 2032 button cell. The slow cycling voltammetry (CV) of CoTMPP electrode shows irreversible O2 reaction instead of Co/Ni electrode where the capacity of oxygen evolution reaction is about 3 times less than of the oxygen reduction reaction. Nevertheless, the obtained reversibility at slow CV, the galvanostatic cycling tests at 1 mA shows irreversibility of the process most probably to the very high polarization at that current.
