In situpreparation of 3D graphene aerogelsierarchical Fe sub(3)O sub(4) nanoclusters as high rate and long cycle anode materials for lithium ion batteries

We describe a novel strategy for in situfabrication of hierarchical Fe sub(3)O sub(4) nanoclusters-GAs. Fe sub(3)O sub(4) NCs-GAs deliver excellent rate capability (the reversible capacities obtained were 1442, 392 and 118 mA h g super(-1) at 0.1C, 12C and 35C rates), and a high reversible capacity...

Zusammenfassung:We describe a novel strategy for in situfabrication of hierarchical Fe sub(3)O sub(4) nanoclusters-GAs. Fe sub(3)O sub(4) NCs-GAs deliver excellent rate capability (the reversible capacities obtained were 1442, 392 and 118 mA h g super(-1) at 0.1C, 12C and 35C rates), and a high reversible capacity of 577 mA h g super(-1) over 300 cycles at the current density of 5.2 A g super(-1) (6C).
