In this work we study heat-treated FeCu-phthalocyanine (FeCuPc) complexes as the catalyst for oxygen reduction in non-aqueous electrolyte Li/air cells by supporting the catalyst on a high surface area Ketjenblack EC-600JD carbon black. It is shown that the resultant FeCu/C catalyst not only accelerates the two-electron reduction of oxygen as “O2 +2Li+ +2e→Li2O2”, but also catalyzes the chemical disproportionation of Li2O2 as “2Li2O2 →2Li2O+O2”. In Li/air cells, the catalyst reduces polarization on discharge while simultaneously reducing the fraction of Li2O2 in the final discharged products. In a 0.2molkg−1 LiSO3CF3 7:3 (wt.) propylene carbonate (PC)/tris(2,2,2-trifluoroethyl) phosphate (TFP) electrolyte, the Li/air cells with FeCu/C show at least 0.2V higher discharge voltage at 0.2mAcm−2 than those with pristine carbon. By measuring the charge-transfer resistance (R ct) of Li/air cells at temperatures ranging between −30°C and 30°C, we determine the apparent activation energy of the discharge of Li/air cells and discuss the effect of FeCu/C catalyst on the oxygen reduction in Li/air cells.
