The integration of active materials into graphene foam (GF) is of fundamental importance for developing superior binder-free electrodes. In the present design, Prussian blue (PB) nanocubes were uniformly grown into the GF network by a facile immersion approach. This is the first example of GF supported metal cyanides and their applications as electrode materials. The as-prepared PB and GF/PB samples have been characterized systematically. This free-standing and flexible GF/PB composite electrode exhibited a high reversible gravimetric (areal) capacity of 514mAh g(-1) (0.47 mAh cm(-2)) at 100 mA g(-1) over 150 cycles and superior cycling stability with 99% capacity retention as well as good rate capability of similar to 150 mAh g(-1) at 1 A g(-1). Such outstanding electrochemical behaviors were attributed to the synergistic integration of both GF and PB components. Thus, the GF/PB system can be employed as potential superior binder-free anode candidates for high-performance lithium-ion batteries. (C) 2018 Elsevier B.V. All rights reserved.
