To evaluate the effect of the pore channel size on battery performance, we employed OMCs possessing two different pore sizes (6 and 17 nm). When cycled at a current density of 200 mA g(carbon)(-1), the OMC electrodes reduced polarization in the oxygen evolution reaction by 0.1 V compared to those consisting of conventional super P carbon electrode. X-ray diffraction and transmission electron microscopy of the discharged oxygen electrodes provided evidence for the formation of amorphous Li2O2, a product of the oxygen reduction reaction, inside the OMC pores rather than on the electrode surface as in the case of the super P electrode. The OMC electrodes were also effective at high current densities (500 mA g(carbon)(-1) and 1000 mA g(carbon)(-1)).  ISSN : 1944-8244  Journal Name : ACS APPLIED MATERIALS & INTERFACES  Volume : 5  Issue Number : 24  Publishing Year : 1434 AH 2013 AD  Article Type : Article  Added Date : Sunday, July 16, 2017  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email J Park Park, J Researcher     J Lee Lee, J Researcher     c Yoon Yoon, c Researcher     y Sun Sun, y Researcher     Files File Name Type Description  42019.pdf pdf   Back To Researches Page
