Iron phthalocyanine supported on graphite nanofibers (GNF_ FePc) were synthesized using a simple solvothermal process and characterized using various structural analyses. GNF_ FePc were employed as bifunctional electrocatalysts in the air cathode of lithium-oxygen batteries. Galvanostatic chargedischarge tests, cyclic voltammetry, and electrochemical impedance spectroscopy were performed to assess the Performance of Li-air batteries. The air-cell delivered a high specific capacity of similar to 5500 mAh/g at the first cycle which remained close to 90% of that value after 4 cycles. The reversibility was nearly 100% for all the four cycles with comparatively lower over potential. (C) 2016 Elsevier Ltd. All rights reserved.
