Abstract

A facile and general method is reported to prepare ordered porous graphene-based binder-free electrodes on a large scale. This preparation process allows the easy adjustment of the selected components, weight ratio of componets, and the thickness of the electrodes. Such ordered porous electrodes demonstrate superior Li storage properties; for example, graphene-Fe3 O4 @C depicts high capacities of 1123.8 and 505 mAh g(-1) at current densities of 0.5 and 10 A g(-1) , respectively.

Keywords: graphene; lithium ion batteries; metal oxides; ordered porous electrodes.
