Heat-treated metal phthalocyanine complex as an oxygen reduction catalyst for non-aqueous electrolyte Li/air batteries

摘要: Abstract 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 on a high surface area Ketjenblack EC-600JD carbon black. It is shown that resultant FeCu/C not only accelerates two-electron of “O 2  + 2Li +  + 2e → Li O ”, but also catalyzes chemical disproportionation Li “2Li  → 2Li O + O ”. cells, reduces polarization discharge while simultaneously reducing fraction final discharged products. 0.2 mol kg −1 LiSO 3 CF 7:3 (wt.) propylene carbonate (PC)/tris(2,2,2-trifluoroethyl) phosphate (TFP) electrolyte, with show at least 0.2 V higher voltage 0.2 mA cm −2 than those pristine carbon. By measuring charge-transfer resistance ( R ct ) temperatures ranging between −30 °C and 30 °C, determine apparent activation energy discuss effect cells.
